DESCRIPTION
The VN800S(8961), VN800PT(8961) 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 V
CC
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.
Device automatically turns off in case of ground
pin disconnection.
