DESCRIPTION

The VN920SP is a mono lithic d evice designe d in 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 integrates an analog current sens e output which delivers a current proportional to the load current. Device autom atically turns off in case of gro und pin disconnection.
