DESCRIPTION
The VN820, VN820SP, VN820-B5, VN820SO,
VN820PT are monolithic devices made by using
STMicroelectronics VIPower M0-3 Technology,
intended for driving any kind of load with one side
connected to ground.
Active VCC pin 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.
The device detects open load condition both is on
and off state. Output shorted to VCC is detected in
the off state. Device automatically turns off in case
of ground pin disconnection.
