产品概述
描述
The device is a quad channel high-side driver manufactured using the latest ST proprietary VIPower® technology and housed in a PowerSSO-36 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 dedicated multifunction multiplexed analog output pin delivers sophisticated diagnostic functions such as 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.
The device features a dedicated LED Mode.
