The VNQ5E050MK-E is a quad channel high-side driver with analog current sense and diagnostic functions for automotive applications. It features power limitation for inrush current, very low standby current, optimized electromagnetic emissions, and low electromagnetic susceptibility.
The VNQ5E050MK-E is a quad channel high-side driver manufactured in ST proprietary ViPower MOO-5 technology and housed in the tiny PowerSSO-24 package. It is designed to drive 12V automotive grounded loads, delivering protection, diagnostics, and easy 3V and 5V CMOS compatible interface with any microcontroller.
The device integrates advanced protective functions such as load current limitation, inrush and overload active management by power limitation, overtemperature shut-off with auto-restart, and over-voltage active clamp. A dedicated analog current sense pin is associated with every output channel to provide enhanced diagnostic functions including fast detection of overload and short-circuit to ground.
