VNQ7140AJ：Quad channel high-side driver with MultiSense analog feedback for automotive applications
The device is a quad channel high-side driver
manufactured using ST proprietary VIPower® 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 sophisticated diagnostic functions including high precision proportional load
current sense, supply voltage feedback and chip temperature 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
