VN7140AJ：Single-channel HSD with analog current sense
The devices are single channel high-side drivers manufactured using ST
proprietary VIPower® M0-7 technology and housed in
PowerSSO-16 and SO-8 packages. The devices are designed to drive 12 V automotive grounded
loads through a 3 V and 5 V CMOS-compatible interface, and to provide protection and
diagnostics.
The devices integrate 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.
