描述 Description

The device is a double channel high-side driver manufactured using ST proprietary VIPower® technology and housed in PowerSSO-12 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.

A current sense 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.
