描述 Description

The device is a single 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, and to provide 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 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.
