DESCRIPTION

The VN610SP is a monolithic device made using

STMicroelectronics VIPower technology. It is

intended for driving resistive or inductive loads

voltage clamp protects the device against low

energy

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.
