Description

The device is a single channel high-side driver manufactured using ST proprietary

VIPower M0-9 technology and housed in a PowerSSO-16 package. The device is

designed to drive 12 V automotive grounded loads through a 3 V and 5 V CMOScompatible

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.
