DESCRIPTION
The VND920 is a double chip device made by
using
STMicroelectronics
VIPower
M0-3
Technology, intended for driving any kind of load
with one side connected to ground. Active V

voltage clamp protects the device against low
energy
spikes
(see
ISO7637
transient
compatibility table). Active current limitation
combined with thermal shutdown and automatic
restart protect the device against overload. Built-
in analog current sense output delivers a current
proportional to the load current. Device
automatically turns off in case of ground pin
disconnection.
