Overview
The VN7040ASTR-E, produced by STMicroelectronics, is a single-channel high-side driver designed for automotive and industrial applications. This device is manufactured using ST's proprietary VIPower M0-7 technology and is available in SO-8 and PowerSSO-16 packages. It 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 VN7040ASTR-E integrates various protective features such as 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 delivers sophisticated diagnostic functions, including high precision proportional load current sense, supply voltage feedback, and chip temperature sense.
