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 low-

power mode as well as external sense resistor sharing among similar devices.
