DESCRIPTION
The VN610SP is a monolithic device made using
STMicroelectronics VIPower technology. It is
intended for driving resistive or inductive loads
with one side connected to ground. Active V

voltage clamp protects the device against low

spikes
(see
ISO7637
transient
compatibility table). This device integrates an
analog current sense which delivers a current
proportional to the load current (according to a
known ratio). Active current limitation combined
with thermal shut-down and automatic restart
protect the device against overload. Device
automatically turns off in case of ground pin
disconnection.
