Description
The VNQ9025AJ is a quad channel high-side driver manufactured using ST
proprietary VIPower M0-9 technology and housed in 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 dedicated multifunction multiplexed analog output pin delivers diagnostic functions
including 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.
