Product Summary

The VNQ05XSP is a monolithic device designed in STMicroelectronics VIPower M0-3 Technology. It is intended for driving any type of multiple loads with one side connected to ground. Active VCC pin voltage clamp protects the VNQ05XSP against low energy spikes. The VNQ05XSP has four independent channels and one multiplexed analog sense output which deliver a current proportional to the selected output current. SenseEnable pin allows to connect any number of VNQ05XSP on the same Current Sense line. Active current limitation combined with thermal shut-down and automatic restart protect the VNQ05XSP against overload. Device automatically turns off in case of ground pin disconnection.
