DESCRIPTION

The VN920D-B5, VN920DSO 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.
