Description
The LITIX™ Basic TLD2311EL is a three channel high side driver IC with integrated output stages. It is designed
to control LEDs with a current up to 120 mA. In typical automotive applications the device is capable to drive
i.e. 3 red LEDs per chain (total 9 LEDs) with a current up to 60 mA, which is limited by thermal cooling aspects.
The output current is controlled practically independent of load and supply voltage changes.

If the voltage at the pin EN is below a threshold of VEN(off) the LITIX™ Basic IC will enter Sleep mode. In this state
all internal functions are switched off, the current consumption is reduced to IS(sleep). A voltage above VEN(on) at

Internal Supply Pin
The EN pin can be used to supply the internal logic. There are two typical application conditions, where this
feature can be used:
1) In “DC/DC control Buck” configurations, where the voltage Vs can be below 5.5V.
2) In configurations, where a PWM signal is applied at the Vbatt pin of a light module. The buffer capacitor CBUF
is used to supply the LITIX™ Basic IC during Vbatt low (Vs low) periods. This feature can be used to minimize
the turn-on time to the values specified in Pos. 9.2.13. Otherwise, the power-on reset delay time tPOR
(Pos. 5.4.8) has to be considered.
The capacitor can be calculated using the following formula:
I EN LS
C BUF = tLOW max -------------------------------------------------V S – V D1 – V S POR

EN Unused
In case of an unused EN pin, there are two different ways to connect it:
5.3.1
EN - Pull Up to VS
The EN pin can be connected with a pull up resistor (e.g. 10 kΩ) to Vs potential. In this configuration the
LITIX™ Basic IC is always enabled.
5.3.2
EN - Direct Connection to VS
The EN pin can be connected directly to the VS pin (IC always enabled). This configuration has the advantage
(compared to the configuration described in Chapter 5.3.1) that no additional external component is
required.

Output Current Adjustment via RSET
The output current of each channel can be adjusted independently. The current adjustment can be done by
placing a low power resistor (RSET) at the IN_SETx pin to ground. The dimensioning of the resistor can be done
using the formula below:
kR SET = ---------I OUT
(2)
The gain factor k (RSET * output current) is specified in Pos. 9.2.4 and Pos. 9.2.5. The current through the RSET
is defined by the resistor itself and the reference voltage VIN_SET(ref), which is applied to the IN_SET during
supplied device.
6.2
Smart Input Pin
The IN_SETx pin can be connected via RSET to the open-drain output of a µC or to an external NMOS transistor
as described in Figure 8. This signal can be used to turn off the output stages of the IC. A minimum IN_SET
current of IIN_SET(act) is required to turn on the output stages. This feature is implemented to prevent glimming
of LEDs caused by leakage currents on the IN_SET pin, see Figure 11 for details. In addition, the IN_SET pin
offers the diagnostic feedback information, if the status pin is connected to GND. Another diagnostic
possibility is shown in Figure 9, where the diagnosis information is provided via the ST pin (refer to Chapter 7
and Chapter 8) to a micro controller. In case of a fault event with the ST pin connected to GND the IN_SET
voltage is increased to VIN_SET(OL/SC) Pos. 8.4.2. Therefore, the device has two voltage domains at the IN_SETpin, which is shown in Figure 12.
Note: If one output has a present fault (open load or short circuit) and one or both of the other channels are
dimmed via PWM at the IN_SET-pins a short spike to VIN_SET(OL/SC) is possible. Please refer to Chapter 8.3.

7.1
Diagnosis Selector
If the status pin is unconnected or connected to GND via a high ohmic resistor (VST to be below VST(L)), the ST
pin acts as diagnosis output pin. In normal operation (device is activated) the ST pin is pulled to GND via the
internal pull down current IST(PD). In case of an open load or short circuit to GND condition the ST pin is
switched to VST(OL/SC) after the open load or short circuit detection filter time (Pos. 8.4.9, Pos. 8.4.12).
If the device is operated in PWM operation via the VS and/or EN pins the ST pin should be connected to GND
via a high ohmic resistor (e.g. 470 kΩ) to ensure proper device behavior during fast rising VS and/or EN slopes.
If the ST pin is shorted to GND the diagnostic feedback is performed via the IN_SET-pin, which is shown in
Chapter 6.2 and Chapter 8.
7.2
Diagnosis Output
If the status pin is unconnected or connected to GND via a high ohmic resistor (VST to be below VST(L)), it acts as
a diagnostic output. In case of a fault condition the ST pin rises its voltage to VST(OL/SC) (Pos. 8.4.7). Details are
shown in Chapter 8.
7.3
Disable Input
If an external voltage higher than VST(H) (Pos. 8.4.5) is applied to the ST pin, the device is switched off. This
function is used for applications, where multiple drivers should be used for one light function. It is possible to
combine the drivers’ fault diagnosis via the ST pins. If a single LED chain fails, the entire light function is
switched off. In this scenario e.g. the diagnostic circuit on the body control module can easily distinguish
between the two cases (normal load or load fault), because nearly no current is flowing into the LED module
during the fault scenario - the drivers consume a current of IS(fault,STu) (Pos. 5.4.5) or IS(dis,ST) (Pos. 5.4.3).
As soon as one LED chain fails, the ST-pin of this device is switched to VST(OL/SC). The other devices used for the
same light function can be connected together via the ST pins. This leads to a switch off of all devices
connected together.

Load Diagnosis
8.1
Open Load
An open load diagnosis feature is integrated in the TLD2311EL driver IC. If there is an open load on one of the
outputs, the respective output is turned off. The potential on the IN_SET pin rises up to VIN_SET(OL/SC), if the ST
is connected to GND. This high voltage can be used as input signal for an µC as shown in Figure 9. If the ST pin
is open or connected to GND via a high ohmic resistor, the ST pin rises to a high potential as described in
Chapter 7. More details are shown in Figure 18. The open load status is not latched, as soon as the open load
condition is no longer present, the output stage will be turned on again. An open load condition is detected, if
the voltage drop over the output stage VPS is below the threshold according Pos. 8.4.10 and a filter time of tOL
is passed.

Short Circuit to GND detection
The TLD2311EL has an integrated SC to GND detection. If the output stage is turned on and the voltage at the
output falls below VOUT(SC) the potential on the IN_SET pin is increased up to VIN_SET(OL/SC) after tSC, if the ST pin
is connected to GND. If the ST is open or connected to GND via a high ohmic resistor the fault is indicated on
the ST pin according to Chapter 7 after tSC. More details are shown in Figure 18. This condition is not latched.
For detecting a normal condition after a short circuit detection an output current according to IOUT(SC) is driven
by the channel.

Double Fault Conditions
The TLD2311EL allows the diagnosis of each channel separately, as long as the ST-pin is shorted to GND. The
diagnosis filter times tOL and tSC (Pos. 8.4.9 and Pos. 8.4.12) are valid only for the channel, which diagnoses
first the fault condition. For the other channel or channels with a subsequential fault the diagnosis is reported
immediately without the diagnosis filter time, if the filter time tOL has been elapsed for the channel with the
first fault. During activation via IN_SET of a non-faulty output, where one channel has already a fault detected,
a short spike to VIN_SET(OL/SC) could occur on the channel, which should be activated. Therefore, in general a
diagnosis should be done earliest after the diagnosis filter times tOL and tSC to avoid any incorrect diagnosis
readout. In the scenario mentioned above the turn on time tON(IN_SET) could be extended. The following figure
shows the example behavior, if OUT1 has a fault and OUT2 is operated in PWM-mode. OUT3 is disabled.

Power Stage
9
Power Stage
The output stages are realized as high side current sources with a current of 120 mA. During off state the
leakage current at the output stage is minimized in order to prevent a slightly glowing LED. To increase the
overall output current for high brightness LED applications it is possible to connect two or all three output
stages in parallel.
The maximum current of each channel is limited by the power dissipation and used PCB cooling areas (which
results in the applications RthJA).
For an operating current control loop the supply and output voltages according to the following parameters
have to be considered:
•
•
•
Required supply voltage for current control VS(CC), Pos. 5.4.10
Voltage drop over output stage during current control VPS(CC), Pos. 9.2.6
Required output voltage for current control VOUTx(CC), Pos. 9.2.7
9.1
Protection
The device provides embedded protective functions, which are designed to prevent IC destruction under fault
conditions described in this data sheet. Fault conditions are considered as “outside” normal operating range.
Protective functions are neither designed for continuous nor for repetitive operation.
9.1.1
Over Load Behavior
An over load detection circuit is integrated in the LITIX™ Basic IC. It is realized by a temperature monitoring of
the output stages (OUTx).
As soon as the junction temperature exceeds the current reduction temperature threshold Tj(CRT) the output
current will be reduced by the device by reducing the IN_SET reference voltage VIN_SET(ref). This feature avoids
LED’s flickering during static output overload conditions. Furthermore, it protects LEDs against over
temperature, which are mounted thermally close to the device. If the device temperature still increases, the
three output currents decrease close to 0 A. As soon as the device cools down the output currents rise again.

V IN_ SET
Tj (C R T)
Figure 20
Tj
Output current reduction at high temperature
Note: This high temperature output current reduction is realized by reducing the IN_SET reference voltage
voltage (Pos. 8.4.1). In case of very high power loss applied to the device and very high junction
temperature the output current may drop down to IOUTx = 0 mA, after a slight cooling down the current
increases again.

Reverse Battery Protection
The TLD2311EL has an integrated reverse battery protection feature. This feature protects the driver IC itself,
but also connected LEDs. The output reverse current is limited to IOUTx(rev) by the reverse battery protection.
Note: Due to the reverse battery protection a reverse protection diode for the light module may be obsolete. In
case of high ISO-pulse requirements and only minor protecting components like capacitors a reverse
protection diode may be reasonable. The external protection circuit needs to be verified in the application.
