Description

The VNQ860-E, VNQ860SP-E are monolithic
devices made using STMicroelectronics VIPower
M0-3 technology, intended for driving any kind of
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 IEC 61131,
(Programmable controllers international
standard).
