Overview
The VND5E050MCJTR-E, produced by STMicroelectronics, is a double-channel high-side driver designed for automotive applications. It is manufactured using ST's proprietary VIPower® M0-5 technology and is housed in a PowerSSO-12 package. This device is optimized to drive 12 V automotive grounded loads, providing advanced protection and diagnostic functions. It features a 3 V and 5 V CMOS-compatible interface, making it compatible with any microcontroller.
The VND5E050MCJTR-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. Each output channel has a dedicated analog current sense pin, enabling enhanced diagnostic functions such as fast detection of overload and short-circuit to ground.
