Description
The VNQ5E050MK-E is a quad channel high-side driver manufactured in the ST proprietary VIPower M0-5 technology and housed in the tiny PowerSSO-24 package. The VNQ5E050MK-E is designed to drive 12V automotive grounded loads delivering protection, diagnostics and easy 3V and 5V CMOS compatible interface with any microcontroller.
