DESCRIPTION

The VNQ600A is a quad HSD formed by assembling two VND600 chips in the same SO-28 package. The VND600 is a monolithic device designed in| STMicroelectronics VIPower M0-3 Technology. The VNQ600A is intended for driving any type of multiple loads with one side connected to ground. This device has four independent channels and four analog sense outputs which deliver currents proportional to the outputs currents. Active current limitation combined with thermal shut-down and automatic restart protect the device against overload. Device automatically turns off in case of ground pin disconnection.
