Overview
The VN5E050AJ-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 12V automotive grounded loads, offering advanced protection, diagnostic capabilities, and a 3V and 5V CMOS compatible interface for easy integration with microcontrollers.
The VN5E050AJ-E integrates various protective functions, including load current limitation, inrush and overload active management by power limitation, over-temperature shutdown with auto-restart, and over-voltage active clamp. It also features a dedicated analog current sense pin for enhanced diagnostic functions such as overload detection, short-circuit detection, and open load detection.
