Description
The device is a double channel high-side driver
manufactured using ST proprietary VIPower®
technology and housed in PowerSSO-12
package. The device is designed to drive 12 V
automotive grounded loads through a 3 V and
5 V CMOS compatible interface, providing
protection and diagnostics.
The device integrates advanced protective
functions such as load current limitation, overload
active management by power limitation and
overtemperature shutdown.
A current sense delivers high precision
proportional load current sense in addition to the
detection of overload and short circuit to ground,
short to VCC and off-state open-load.
A sense enable pin allows off-state diagnosis to
be disabled during the module low-power mode
as well as external sense resistor sharing among
similar devices.

Protections
3.1
Power limitation
Protections
The basic working principle of this protection consists of an indirect measurement of the
junction temperature swing ΔTj through the direct measurement of the spatial temperature
gradient on the device surface in order to automatically shut off the output MOSFET as
soon as ΔTj exceeds the safety level of ΔTj_SD. The output MOSFET switches on and
cycles with a thermal hysteresis according to the maximum instantaneous power which can
be handled. The protection prevents fast thermal transient effects and, consequently,
reduces thermo-mechanical fatigue.
3.2
Thermal shutdown
In case the junction temperature of the device exceeds the maximum allowed threshold
(typically 175°C), it automatically switches off and the diagnostic indication is triggered. The
device switches on again as soon as its junction temperature drops to TR.
3.3
Current limitation
The device is equipped with an output current limiter in order to protect the silicon as well
as the other components of the system (e.g. bonding wires, wiring harness, connectors,
loads, etc.) from excessive current flow. Consequently, in case of short circuit, overload or
during load power-up, the output current is clamped to a safety level, ILIMH, by operating the
output power MOSFET in the active region.
3.4
Negative voltage clamp
In case the device drives inductive load, the output voltage reaches a negative value during
turn off. A negative voltage clamp structure limits the maximum negative voltage to a
certain value, VDEMAG, allowing the inductor energy to be dissipated without damaging the
device.

Figure 32: Simplified internal structure - GND network protection with MOSFET
4.1.1
Diode (DGND) in the ground line
A resistor (typ. RGND = 4.7 kΩ) should be inserted in parallel to DGND if the device drives an
inductive load.
This small signal diode can be safely shared amongst several different HSDs. Also in this
case, the presence of the ground network produces a shift (»600 mV) in the input threshold
and in the status output values if the microprocessor ground is not common to the device
ground. This shift does not vary if more than one HSD shares the same diode/resistor
network.
To comply with LV124, E-11 "severe" start pulse, a Schottky diode (see Figure 31:
"Simplified internal structure - GND network protection with Schottly diode") or N-channel
MOSFET (see Figure 32: "Simplified internal structure - GND network protection with
MOSFET") is recommended in order to ensure a lower ground network shift (≤ 350 mV).
4.2
Immunity against transient electrical disturbances
The immunity of the device against transient electrical emissions, conducted along the
supply lines and injected into the VCC pin, is tested in accordance with ISO7637-2:2011 (E)
and ISO 16750-2:2010.
The related function performance status classification is shown in Table 13: "ISO 7637-2 electrical transient conduction along supply line".
Test pulses are applied directly to DUT (Device Under Test) both in ON and OFF-state and
in accordance to ISO 7637-2:2011(E), chapter 4. The DUT is intended as the present
device only, without components and accessed through VCC and GND terminals.

Status II is defined in ISO 7637-1 Function Performance Status Classification (FPSC) as
follows: “The function does not perform as designed during the test but returns
automatically to normal operation after the test”.

MCU I/Os protection
If a ground protection network is used and negative transients are present on the VCC line,
the control pins will be pulled negative. ST suggests to insert a resistor (Rprot) in line both to
prevent the microcontroller I/O pins to latch-up and to protect the HSD inputs.
The value of these resistors is a compromise between the leakage current of
microcontroller and the current required by the HSD I/Os (Input levels compatibility) with
the latch-up limit of microcontroller I/Os.
Equation
VCCpeak/Ilatchup ≤ Rprot ≤ (VOHµC - VIH - VGND) / IIHmax
Calculation example:
For VCCpeak = -150 V; Ilatchup ≥ 20 mA; VOHµC ≥ 4.5 V
7.5 kΩ ≤ Rprot ≤ 140 kΩ.
Recommended values: Rprot = 15 kΩ
4.4
Behaviour during engine start transients
The battery voltage drops every time an engine start occurs as well as in start&stop
automotive systems.
The device is designed to operate during engine start pulses without external components.
In particular, the device achieves functional status A, for both E-11 start pulses, “normal”
and “severe” as defined in Table 14: "Test parameters, E-11 Start pulses".

Functional status A is defined as follows: the DUT (device under test) must fulfill all
functions during and after exposure to the test parameters.

CurrentSense - analog current sense
Diagnostic information on device and load status are provided by an analog output pin
(CurrentSense) delivering a current mirror of channel output current

Current monitor
This output is capable of providing:
•
•
Current mirror proportional to the load current in normal operation, delivering
current proportional to the load according to known ratio named K
Diagnostics flag in fault conditions delivering fixed voltage VSENSEH
The current delivered by the current sense circuit, ISENSE, can be easily converted to a
voltage VSENSE by using an external sense resistor, RSENSE, allowing continuous load
monitoring and abnormal condition detection.
Normal operation (channel ON, no fault, SEn active)
While device is operating in normal conditions (no fault intervention), VSENSE calculation can
be done using simple equations
Current provided by CurrentSense output: ISENSE = IOUT/K
Voltage on RSENSE : VSENSE = RSENSE . ISENSE = RSENSE . IOUT/K
Where :
•
VSENSE is voltage measurable on RSENSE resistor

Application information

•
VND7140AJ12
ISENSE is current provided from CurrentSense pin in current output mode
IOUT is current flowing through output
K factor represents the ratio between PowerMOS cells and SenseMOS cells; its
spread includes geometric factor spread, current sense amplifier offset and process
parameters spread of overall circuitry specifying ratio between IOUT and ISENSE.
Failure flag indication
In case of power limitation/overtemperature, the fault is indicated by the CurrentSense pin
which is switched to a “current limited” voltage source, VSENSEH.
In any case, the current sourced by the CurrentSense in this condition is limited to ISENSEH.
The typical behavior in case of overload or hard short circuit is shown in Waveforms
section.

Short to VCC and OFF-state open-load detection
Short to VCC
A short circuit between VCC and output is indicated by the relevant current sense pin set to
VSENSEH during the device off-state. Small or no current is delivered by the current sense
during the on-state depending on the nature of the short circuit.
OFF-state open-load with external circuitry
Detection of an open-load in off mode requires an external pull-up resistor RPU connecting
the output to a positive supply voltage VPU.
It is preferable VPU to be switched off during the module standby mode in order to avoid the
overall standby current consumption to increase in normal conditions, i.e. when load is
connected.
