Overview
The VNQ5E160AK-E is a quad channel high-side driver manufactured by STMicroelectronics using their proprietary VIPower M0-5 technology. It is housed in the compact PowerSSO-24 package. This device is designed to drive 12V automotive grounded loads, offering advanced protection, diagnostics, and a 3V and 5V CMOS compatible interface with any microcontroller. It integrates various protective functions such as load current limitation, inrush and overload active management, over-temperature shut-off with auto-restart, and over-voltage active clamp. Each output channel has a dedicated analog current sense pin for enhanced diagnostic functions, including fast detection of overload and short-circuit conditions.
