Description
The VN920-B5H is a monolithic device 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 able).
Active current limitation combined with thermal shutdown and automatic restart protect the device against overload. The device integrates an analog current sense output which delivers a current proportional to the load current. Device automatically turns off in case of ground pin disconnection.
