DESCRIPTION

The VNQ810 is a quad HSD formed by
assembling two VND810 chips in the same SO-28
package. The VND810 is a monolithic device
made by using STMicroelectronics VIPower M0-3
Technology, intende d for d riving any k ind of l oad
with one side connected to ground.
Active VCC pin voltag e clamp protects th e dev ice

against low energy spikes (see ISO7637 transient
compatibility table). Active current limitation
combined with thermal sh utdown and automatic
restart protects the device against overloa d. The
device detects open load condition both in on and
off state . Output shorted to VCC is detected in the
off state. Dev ice auto matic ally tur ns off in cas e of
ground pin disconnection.
