channels and four analog sense outputs which deliver currents proportional to the outputs

DESCRIPTION

The VNQ600A is a quad HSD formed by assembling two VND600 chips in the same SO-28

currents. Active current limitation combined with thermal shut-down and automatic restart protect the device against overload . Device auto mati call y turns off in case of ground pin disconnection.
