Overview
The VN5E050MJ-E is a single-channel high-side driver manufactured by STMicroelectronics using their proprietary VIPower™ M0-5 technology. It is housed in the compact PowerSSO-12 package. This device is designed to drive 12 V automotive grounded loads, offering advanced protection, diagnostic capabilities, and a 3 V and 5 V CMOS compatible interface for easy integration with microcontrollers.
The VN5E050MJ-E integrates various protective functions, including load current limitation, inrush and overload active management by power limitation, overtemperature shutdown with auto-restart, and overvoltage active clamp. It also features a dedicated analog current sense pin for enhanced diagnostic functions such as fast detection of overload and short-circuit to ground.
