♠ High-side driver with MultiSense analog feedback for automotive applications
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 lowpower mode as well as external sense resistor sharing among similar devices.
