Product overview
Description
The VN820 is a monolithic device designed in STMicroelectronic's VIPower®M0-3 technology. The VN820 is intended for driving any type of load with one side connected to ground. The active VCCpin voltage clamp protects the device against low energy spikes.
Active current limitation combined with thermal shutdown and automatic restart protects the device against over-load. The device detects the open-load condition in both the on-state and off-state. In the off-state the device detects if the output is shorted to VCC. The device automatically turns off in the case where the ground pin becomes disconnected.
