Overview
The VNQ05XSP16 is a monolithic device designed by STMicroelectronics using the VIPower M0-3 Technology. This quad-channel high-side solid-state relay is intended for driving various types of multiple loads with one side connected to ground. It features active VCC pin voltage clamp protection against low energy spikes and complies with ISO7637 transient compatibility standards. The device includes four independent channels and a multiplexed analog sense output that delivers a current proportional to the selected output current. The SenseEnable pin allows multiple VNQ05XSP16 devices to be connected on the same Current Sense line, enhancing flexibility in system design.
