Product overview
Description
The device is single channel high-side driver manufactured using ST proprietary VIPower® M07 technology and housed in the SO-8 package. It 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.A dedicated Multisense pin delivers 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.
