Overview
The VN7040AJTR from STMicroelectronics is a single-channel smart high-side driver designed for automotive applications. It is manufactured using ST's proprietary VIPower M0-7 technology and is available in PowerSSO-16 and SO-8 packages. This device is engineered to drive 12 V automotive grounded loads through a 3 V and 5 V CMOS-compatible interface, providing advanced protection and diagnostic functions.
The VN7040AJTR integrates multiple protective features, including load current limitation, overload active management by power limitation, and overtemperature shutdown with configurable latch-off. It also includes a FaultRST pin to unlatch the output in case of a fault or to disable the latch-off functionality. A dedicated multifunction multiplexed analog output pin offers sophisticated diagnostic functions such as load current sense, supply voltage feedback, and chip temperature sense.
