Description
Block_diag_10ch_TLE8110.vsd
Communication
The TLE8110EE is a 10-channel low-side switch in PG-DSO-36 package providing embedded protection
functions. The 16-bit serial peripheral interface (SPI) can be utilized for control and diagnosis of the device and
the loads. The SPI interface provides daisy-chain capability in order to assemble multiple devices in one SPI chain
by using the same number of micro-controller pins 1).
The analogue and the digital part of the device is supplied by 5V. Logic Input and Output Signals are then
compatible to 5V logic level [TTL - level]. Optionally, the logic part can be supplied with lower voltages to achieve
signal compatibility with e.g. 3.3V logic level [CMOS - level].
The TLE8110EE is equipped with 10 parallel input pins that are routed to each output channel. This allows control
of the channels for loads driven by Pulse Width Modulation (PWM). The output channels can also be controlled
by SPI.
Reset
The device is equipped with one Reset Pin and one Enable. Reset [RST] serves the whole device, Enable [EN]
serves only the Output Control Unit and the Power Stages.

Diagnosis
The device provides diagnosis of the load, including open load, short to GND as well as short circuit to VBatt
detection and over-load / over-temperature indication. The SPI diagnosis flags indicates if latched fault conditions
may have occurred.
Protection
Each output stage is protected against short circuit. In case of over load, the affected channel is switched off. The
switching off reaction time is dependent on two switching thresholds. Restart of the channel is done by clearing
the Diagnosis Register 1). This feature protects the device against uncontrolled repetitive short circuits. The
reaction to a short-circuit and over-temperature can be alternatively changed to further modes, such as semi- or
auto - restart of the affected channel.
There is a temperature sensor available for each channel to protect the device in case of over temperature. In case
of over temperature the affected channel is switched off and the Over-Temperature Flag is set. Restart of the
channel is done by deleting the Flag. This feature protects the device against uncontrolled temperature toggling.
Parallel Connection of Channels
The device is featured with a central clamping structure, so-called CLAMPsafe. This feature ensures a balanced
clamping between the channels and allows in case of parallel connection of channels a high efficient usage of the
channel capabilities. This parallel mode is additionally featured by best possible parameter- and thermal matching
of the channels and by controlling the channels accordingly.

Block Diagram Supply and Reset
Description Supply
The Supply Voltage Pins are monitored during the power-on phase and under normal operating conditions for
under voltage.
If during Power-on the increasing supply voltage exceeds the Supply Power-on Switching Threshold, the internal
Reset is released after an internal delay has expired.
In case of under voltage, a device internal reset is performed. The Switching Threshold for this case is the Poweron Switching threshold minus the Switching Hysteresis.
In case of under voltage on the analogue supply line VDD the outputs are turned off but the content of the registers
and the functionality of the logic part is kept alive. In case of under voltage on the digital supply VCC line, a complete
reset including the registers is performed.
After returning back to normal supply voltage and an internal delay, the related functional blocks are turned on
again. For more details, refer to the chapter “Reset”.
The device internal under-voltage set will set the related bits in SDS (Short Diagnosis and Device Status) to allow
the micro controller to detect this reset. For more information, refer to the chapter “Control of the Device”.

Reset and Enable Inputs
6.1
Description Reset and Enable Inputs
The TLE8110EE contains one Reset- and one Enable Input Pin as can be seen in Figure 6.
Description:
Reset Pin [RST] is the main reset and acts as the internal under voltage reset monitoring of the digital supply
voltage VCC: As soon as RST is pulled low, the whole device including the control registers is reset.
The Enable Pin [EN] resets only the Output channels and the control circuits. The content of the all registers is
kept. This functions offers the possibility of a “soft” reset turning off only the Output lines but keeping alive the SPI
communication and the contents of the control registers. This allows the read out of the diagnosis and setting up
the device during or directly after Reset.

Power Outputs
7.1
Description Power Outputs
The TLE8110EE is a 10 channel low-side powertrain switch. The power stages are built by N-channel power
MOSFET transistors. The device is a universal multichannel switch but mostly suited for the use in Engine
Management Systems [EMS]. Within an EMS, the best fit of the channels to the typical loads is:
•
•
•
Channel 1 to 4 for Injector valves or mid-sized solenoids with a nominal current requirement of 1.5A.
Channel 5 to 6 for mid-sized solenoids or Injector valves with a nominal current requirement of 1.7A
Channel 7 to 10 for small solenoids or relays with a nominal current requirement of 0.75A
Channel 1 to 10 provide enhanced clamping capabilities of typically 55V best suited for inductive loads such as
injectors and valves. It is recommended in case of an inductive load, to connect an external free wheeling- or
clamping diode, where-ever possible to reduce power dissipation.
All channels can be connected in parallel. Channels 1 to 4, 5 to 6 and 7 to 10 are prepared by matching for parallel
connection with the possibility to use a high portion of the capability of each single channel also in parallel mode
(refer to Chapter 7.4).
Channel 5 and 6 have a higher current shut down threshold to allow to connect in parallel mode a load with a high
inrush-current, such as a lambda sensor heater.

Description of the Clamping Structure
When switching off inductive loads, the potential at pin OUT rises to VDS(CL) potential, because the inductance
intends to continue driving the current. The clamping voltage is necessary to prevent destruction of the device,
see Figure 9 for the clamping circuit principle. Nevertheless, the maximum allowed load inductance is limited.

Internal Clamping Principle
Clamping Energy
During demagnetization of inductive loads, energy has to be dissipated in the device. This energy can be
calculated with following equation:
RL ⋅ IL
LL
V DS ( CL ) – V BAT
E = V DS ( CL ) ⋅ ------ ⋅ I L – ------------------------------------- ⋅ ln ⎛ 1 + ------------------------------------⎞
⎝
RL
RL
V DS ( CL ) – V BAT⎠
(1)
The maximum energy, which is converted into heat, is limited by the thermal design of the component.
Attention: It is strongly recommended to measure the load Energy and Current under operating
conditions, example of measurement setup is shown in Figure 10. Load small-signal
parameters might not reflect the real load behavior under operating conditions, see Figure 11.
For more details please refer to the Application Note “Switching Inductive Loads”.

Parallel Connection of the Power Stages
Timing_Power_Outx _res1.vsd
The TLE8110EE is equipped with a structure which improves the capability of parallel-connected channels. The
device can be “informed” via the PMx.PMx - bits (see chapter control of the device) which of the channels are
connected in parallel. The input channels can be mapped to the parallel connected output channels in order to
apply the PWM signals. This feature allows a flexible adaptation to different load situations within the same
hardware setup.
In case of overload the ground current and the power dissipation is increasing. The application has to take into
account that all maximum ratings are observed (e.g. operating temperature TJ and total ground current IGND, see
Maximum Ratings). In case of parallel connection of channels with or w/o PM-bit set, the defined maximum
clamping energy must not be exceeded.
All stages are switched on and off simultaneously. The µC has to ensure that the stages which are connected in
parallel have always the same state (on or off). The PM-bit should be set according to the parallel connected power
stages in order to achieve the best possible performance.
The PM-bit is set to its default value in case of a Reset event (Reset pin Low or at Digital Supply undervoltage),
that means the improved Parallel Mode is no longer active. In the event of reset the channels will be switched off
causing the clamping energy to be dissipated with low performance of the current sharing as without PM-bit set,
for more details please refer to the Application Note Switching Inductive Loads - TLE8110 addendum.
The performance during parallel connection of channels is specified by design and not subject to the production
test. All channels at the same junction temperature level.

1) No priority scheme is implemented for the diagnosis detection, any new diagnosis entry will override the previous one
2) Diagnosis Register (A/B banks) bit configuration, see Chapter 12.3.2.1
3) For some diagnosis a confirmation procedure is required for a safe operation of the device, refer to Figure 17
Updating of the Diagnosis is based on a filter-dependent standard delay time (td) of 220µs max. This value is set
as a default. Refer to Figure 18 for details.
If SCG or OL condition is asserted and before the Diagnosis Delay Time (td) is elapsed a condition change occurs,
OL-to-SCG or SCG-to-OL, filter timer is not reset and latest condition before td expiration will be stored into the
diagnosis register.
•
Application Hint: It is recommended to avoid OFF periods of the channel shorter than td(max) (220µs) in order
to ensure the filter time is expired and the correct diagnosis information is stored.
•
Application Hint: In specific application cases - such as driving Uni-Polar Stepper Motor - it might be possible,
that reverse currents flow for a short time, which possibly can disturb the diagnosis circuit at neighboring
channels and cause wrong diagnosis results of those channels. To reduce the possibility, that this effect
appears in a certain timing range, the filter time of Channels 7 to 10 can be extended to typ. 2.5ms or typ. 5ms
by setting the “Diagnosis Blind Time” - Bits (DBTx). If Channels 7 to 10 are used for driving loads causing
reverse currents, they influence each other and additionally might affect Channels 5 and 6 . It is recommended
to use the channels 7 + 8 and 9 + 10 as pairs for anti-parallel control signals, such as for the stepper motors.
For logic setting details, see chapter “Control of the Device”.

There are 10 input pins available are on TLE8110EE to control the output stages.
Each input signal controls the output stages of its assigned channel. For example, IN1 controls OUT1, IN2 controls
OUT2, etc.
A “Low”-Signal at INx switches the related Output Channel off. The zener diode protects the input circuit against
ESD pulses.

Protection Functions
10
Protection Functions
The device provides embedded protective functions. Integrated protection functions are designed to prevent IC
destruction under fault conditions described in this Document. Fault conditions are considered “outside” the
normal operating range. Protection functions are not designed for continuous repetitive operation.
There is an over load and over temperature protection implemented in the TLE8110EE.
If a protection function becomes active during the write cycle of Diagnosis Information into the Diagnosis Register,
the information is latched and stored into the diagnosis register after the write process.
In order to achieve a maximum protection, the affected channel with over current or over temperature (OCT) is
switched and latched OFF, channel can be turned ON again after the diagnosis register is cleared
(Chapter 12.3.2) or if a different new diagnosis overrides the OCT.
For the failure condition of Reverse Currents, the device contains a “Reverse Current Protection Comparator”
[RCP]. This RCP can optionally be activated by setting the DEVS.RCP Bit.
In case the comparator is activated, it detects a reverse current and switches ON the related output channel. The
channel is kept ON up to a reverse current channel dependent threshold IRCP_off. This threshold is defined by
regulators target value to keep the output voltage at >/~-0.3V. If the current exceeds a defined value, the
comparator switches OFF and other protection functions are protecting the circuit against reverse current. That
means that at higher currents / or in case RCP is de-activated / not activated, the reverse current is flowing through
the body diode of the DMOS. In that case, the voltage drops to typically -0.6V according the voltage of the body
diode. In case the comparator threshold has been exceeded and the RCP has been switched OFF, the functions
remains OFF until the reverse current arrives back to zero reverse current. Only then, the comparator can be
activated again after a delay time tRCP_on_delay.
This function reduces the un-wanted influence of a reverse current to the analogue part of the circuit (such as the
diagnosis). For more details about the functionality, see Figure 23 and Figure 24 and concerning the settings and
the related registers, refer to Chapter “Control of the Device”.

16 bit SPI Interface
11.1
Description 16 bit SPI Interface
The diagnosis and control interface is based on a serial peripheral interface (SPI).
The SPI is a full duplex synchronous serial slave interface, which uses four lines: S_SO, S_SI, S_CLK and S_CS.
Data is transferred by the lines S_SI and S_SO at the data rate given by S_CLK. The falling edge of S_CS
indicates the beginning of a data access. Data is sampled in on line S_SI at the falling edge of S_CLK and shifted
out on line SO at the rising edge of SCLK. Each access must be terminated by a rising edge of S_CS. A modulo
8 counter ensures that data is taken only, when a multiple of 8 bit has been transferred. If in one transfer cycle not
a multiple of 8 bits have been counted, the data frame is ignored. The interface provides daisy chain capability.

SPI Interface. Signals and Protocol
12.2.1
Description 16 bit SPI Interface Signals
S_CS - Chip Select:
The system micro controller selects the TLE8110EE by means of the S_CS pin. Whenever the pin is in low state,
data transfer can take place. When S_CS is in high state, any signals at the S_CLK and S_SI pins are ignored
and S_SO is forced into a high impedance state.
S_CS High to Low transition:
•
•
The information to be transferred loaded into the shift register (16-bit Protocol).
S_CS Low to High transition:
•
Command decoding is only done, when after the falling edge of CS exactly a multiple (1, 2, 3, …) of eight
S_CLK signals have been detected. (See Modulo-8 Counter: Chapter 12.2.4.2)
Data Sheet

Rev. 1.4, 2013-07-02
TLE 8110 EE
Smart Multichannel Switch
Control of the device
S_CLK - Serial Clock:
This input pin clocks the internal shift register. The serial input (S_SI) transfers data is shifted into the register on
the falling edge of S_CLK while the serial output (S_SO) shifts the information out on the rising edge of the serial
clock. It is essential that the S_CLK pin is in low state whenever chip select CS makes any transition.
S_SI - Serial Input:
Serial input data bits are shifted in at this pin, the most significant bit first. The bit at the S_SI Pin is read on the
falling edge of S_CLK.
S_SO Serial Output:
Data is shifted out serially at this pin, the most significant bit first. S_SO is in high impedance state until the S_CS
pin goes to low state.The next bits will appear at the S_SO pin following the rising edge of S_CLK.
12.2.2
Daisy Chain
The SPI-Interface of TLE8110EE provides daisy chain capability, see Chapter 12.2.3.4 for more details. In this
configuration several devices are activated by the same S_CS signal. The S_SI line of one device is connected
with the S_SO line of another device (see Figure 27), which builds a chain. The ends of the chain are connected
with the output and input of the master device, S_SO and S_SI respectively. The master device provides the
master clock CLK, which is connected to the S_CLK line of each device in the chain. By each clock edge on
S_CLK, one bit is shifted into the S_SI. The bit shifted out can be seen at SO. After 16 S_CLK cycles, the data
transfer for one device has been finished. In single chip configuration, the S_CS line must go high to make the
device accept the transferred data. In daisy chain configuration the data shifted out at device 1 has been shifted
in to device 2. Example: When using three devices in daisy chain, three times 16 bits have to be shifted through
the devices. After that, the S_CS line must go high (see Figure 27).

12.2.3
SPI Protocol
The device contains two protocol styles which are applied dependent of the used commands. There is the
standard 16-bit protocol and the 2x8-bit protocol. Both protocols can appear also be mixed.
12.2.3.1
16-bit protocol
Each Cycle where a serial data or command frame is sent to the S_SI of the SPI interface, a data frame is returned
at the same time by the S_SO The content of the S_SO frame is dependent on the previous command which has
been sent to S_SI. Read Command (R/W = R) returns one cycle later the content of the addresses register. (see
Figure 28 ).

Note: Reading a register needs two SPI frames. In the first frame the RD command is sent. In the second frame the output at
SPI signal SO will contain the requested information. A new command can be executed in the second frame.
12.2.3.2
2x8-bit protocol
Each Cycle where a serial data or command frame is sent to the S_SI of the SPI interface, a data frame is returned
at the same time by the S_SO. The content of the S_SO frame is dependent of the previous command which has
been sent to S_SI and the content of the actual content of S_SI: The first Upper Byte send to S_SI controls the
content of the Lower Byte actual returned by S_SO. The Lower Byte send to S_SI controls the Lower Byte in S_SO
of the next frame. (see Figure 29 ).

12.2.3.3
16- and 2x8-bit protocol mixed.
The 16-bit and 2x8-bit protocols are mixed according the used commands (see Chapter 12.3.1). Special care
should be taken, changing from the 16-bit protocol to the 2x8-bit protocol. In this case, it is important to send a
NOP command to S_SI. Otherwise, by sending instead a Command, a collision between the S_SO data in the
following frame and the Lower Byte of the 2x8-bit protocol will happen (see Chapter 12.2.3.2).

Daisy-Chain and 2x8-bit protocol
When using the TLE8110EE in a daisy-chain connection with other devices (TLE8110EE and non) special care
has to be taken to avoid interference of 2x8-bit protocol with normal communication. Few simplified rules must be
followed for a safe SPI communication in daisy-chain environment:
1. All TLE8110EE devices have to be routed at the beginning of the chain, other devices than TLE8110EE
afterward
2. compactCONTROL commands (2x8-bit protocol) must not be addressed to TLE8110EE
3. The SPI frame of the daisy-chain must be extended of additional 8-bit (all zeros 00H) at beginning of the frame
4. When a Read/Clear Diagnosis Register A command (DRA, DRACL) is addressed to TLE8110EE, a NOP
command must be sent to the next TLE8110EE on the chain
5. When a Read/Clear Diagnosis Register A command (DRA, DRACL) is addressed to TLE8110EE, response of
the next device on the chain must be ignored in the next SPI cycle

safeCOMMUNICATION
The device contains some safety features, which are improving the protection of the application against malfunction in case of disturbance of the communication between the Micro Controller and the Device:
12.2.4.1
Encoding of the commands
The Commands are encoded. In case other bit-patterns, then the defined once are received, the commands are
ignored and the communication error can be read out with the command CMD_RSDS (seeChapter 12.3.1.2).
12.2.4.2
Modulo-8 Counter
The modulo is the integral remainder in integral division. In data communications, a modulo based approach is
used to ensure that user information in SPI protocols is in the correct order. The device has a receiver-side
counter, and a defined counter size. The modulo counter specifies the number of subsequent numbers available.
In case of TLE8110EE Modulo 8 counter specifies 8 serial numbers. The modulo 8 counter ensures that data is
taken only, when a multiple of 8 bit has been transferred. If in one transfer cycle not a multiple of 8 bits have been
counted, the data frame is ignored and a Communication Error is indicated in the CMD_RSDS - Feedback
(seeChapter 12.3.1.2).
12.3
Register and Command - Overview
This Chapter describes the Registers and Commands. The commands allow to carry through some actions, such
as reading out or clearing the diagnosis or reading out the Input Pins.
Specially highlighted here should be the encoded CMD_DMSx/OPSx commands - compactCONTROL -, a highly
efficient command-set to set a part of the output pins and read out the diagnosis at the same time. Included in this
command set is the possibility to check, if the communication works well as also the possibility to read-out some
of the parallel Input Pins INx. Using this compact command set can reduce the workload of the micro-controller
during run-time significantly.
CMD_RSD is preformed and short diagnostics [SD] is returned after each Write Cycle to any of the writable
registers.
After start-up of the device, the registers are loaded with the default settings as described below in the register
descriptions. The Registers are cleared and set back to the default values, when a low signal is applied to the pin
RST or an under-voltage condition appears at the supply pin VCC what causes an under-voltage reset. If a low
signal at pin EN is applied or an under-voltage condition appears at pin VDD, the Registers are not cleared.

DCC - Diagnosis Registers and compactCONTROL
The DCC - Diagnosis and Compact Control Set allows to read out and clear the Diagnosis Registers. Additionally
this Command set offers the possibility to proceed with a compactCONTROL Mode using DMS - Diagnosis Mode
Set and OPS - Output Pin Set Commands. This compactCONTROL Mode offers the possibility to Control the
device with lowest work load on the micro controller side.
If any other pattern then the defined commands is received on S_SI, the command is ignored and rated as a
Communication Error. In this case, this incident is reported in SDS (Chapter 12.3.1.2).
If an Error in the Output Channels is detected by the diagnosis circuit, the result is latched in the diagnosis registers
related to each channel.
The Diagnosis Register is not deleted, when it is just read out. The Diagnosis Register byte can only be cleared
by using the appropriated command. In this case, the complete Register Bank is cleared.
When issuing a Diagnosis Register Clear command (DRxCL or DMSCL), the idle time tDidle needs to elapse, from
the CS low-to-high transition of the clear command, before the register content is effectively cleared (Figure 40);
this time has to be taken into account when trying to read the Diagnosis register content after a clear, see
Chapter 11.3 for tDidle definition.
After an overcurrent entry is stored in the diagnosis register (OC), the idle time tOCidle needs to elapse before a
clear command can effectively clear the entry; if trying to clear the Diagnosis register after an OCT entry is read
(Figure 40), this time has to be taken into account starting from the CS high-to-low transition of the previous read
command, see Chapter 11.3 for tOCidle definition.

Control of the device
Each Cycle where a serial data or command frame is sent to the Serial Input [SI] of the SPI interface, a data frame
is returned immediately by the Serial Output [SO]. The content of the SO frame is dependent of the previous
command which has been sent to SI and the content of the actual content of SI: The first Byte send by S_SI
controls the content of the second byte actual returned by S_SO. The second Byte send by S_SI controls the first
byte in S_SO of the next frame. (see Figure 42)

Principally, OPF can return the previously send OPS word and the IN

- If Serial Mode is selected by one or more OPS[3:0]-bits, the related
OPF[7:4]-bits are returning the settings of OPS[7:4], send at the
previous frame.
- if parallel Mode is selected by one or more OPS[3:0]-bits, the related
OPF[7:4]-bits are returning the condition available at the related
IN 10:7 Pins at the moment of S_CS high-to-low transition.
A mix of both modes is possible and depends on the channel related
settings.

PMx - Parallel Mode Register CHx
The Parallel Mode Register PMx[1] allows to “inform” the device about externally parallel connected output

best possible matching and according to that highest efficiency of both channels. Additionally to that, the
CLAMPsafe feature allows high matching during clamping.

Controlling Parallel Mode is possible between Channel 1 to 4, 5 to 6,
7 to 10. In between the groups, no parallel mode is supported
but possible.
In case Parallel Mode is chosen and a diagnosis error at only one of
the channels is detected, the according diagnosis bit is set. This
information mismatch can be caused by tolerance related inbalance of the channels connected together in parallel mode.
The diagnosis bits should be or-operated by the Micro Controller
side.
