The VN920SP-E is a monolithic device designed in STMicroelectronics™ VIPower™ M0-3 technology. The VN920SP-E is intended for driving any type of load with one side connected to ground. The 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 protects the device against overload.
The device integrates an analog current sense output which delivers a current proportional to the load current. The device automatically turns-off in the case where the ground pin becomes disconnected.
