DESCRIPTION

The VNQ860, VNQ860SP are monolithic devices

Technology, intended for driving any kind load

with one side connected to ground. Active current

limitation combined with thermal shutdown and

automatic restart protect the device against

overload. Device automatically turns off in case of

ground

pin

disconnection.

This

device

is

especially suitable for industrial applications in

norms conformity with IEC1131 (Programmable

Controllers International Standard).
