VND7E050AJ
Description
The device is a dual channel high-side driver manufactured with proprietary ST
VIPower® M0-7 technology, in a PowerSSO-16 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 with
configurable latch-off.
A FaultRST pin unlatches the output in case of fault or disables the latch-off
functionality.
A multiplexed current sense pin 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.

VCC Battery connection.
OUTPUT0,1 Power outputs; all the pins must be connected together.
GND Ground connection; must be reverse battery protected by an external diode / resistor network.
INPUT0,1
Voltage controlled input pin with hysteresis, compatible with 3 V and 5 V CMOS outputs; controls output switch
state.
CS
Analog current sense output pin; delivers a current proportional to the selected load current, supply voltage or
chip temperature diagnostic.
SEn Active high compatible with 3 V and 5 V CMOS outputs pin; enables the CS diagnostic pin.
SEL0 Active high compatible with 3 V and 5 V CMOS outputs pin; it addresses the CS multiplexer.
FaultRST
Active low compatible with 3 V and 5 V CMOS outputs pin; it unlatches the output in case of fault - if kept low,
sets the outputs in auto-restart mode.
