Description

The VN800PS-E is monolithic device made by
using STMicroelectronics™ VIPower™ M0-3
technology, intended for driving any kind of load
with one side connected to ground.

Active V
against low energy spikes. 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.

pin voltage clamp protects the device

CC

This device is especially suitable for industrial
applications in norms conformity with IEC1131
(Programmable Controllers International
Standard).

must be used together with a proper software strategy. If the device is subjected to abnormal conditions, this software must
limit the duration and number of activation cycles.
