Overview
The VNQ5E050MKTR-E is a quad channel high-side driver manufactured by STMicroelectronics using their proprietary VIPower™ M0-5 technology. It is housed in a PowerSSO-24 package and is designed to drive 12 V automotive grounded loads. The device provides advanced protection and diagnostic functions, along with a 3 V and 5 V CMOS compatible interface, making it compatible with any microcontroller.
The VNQ5E050MKTR-E integrates various protective features such as load current limitation, inrush and overload active management by power limitation, overtemperature shut-off with auto-restart, and overvoltage active clamp. Each output channel has a dedicated analog current sense pin, enabling enhanced diagnostic functions including fast detection of overload and short-circuit to ground.
