DESCRIPTION

The VN920DSP is a monolithic device ma de by using STMicroelectronics VIPower M0-3 Technology, i ntended for dr iving any kind o f load with one side connected to ground. Active VCC pin voltage clamp prote cts 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.
