Description
The VND920 is a double chip device designed in STMicroelectronics VIPower M0-3 technology. The VND920 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 over-load.

Features
■ CMOS compatible input
■ Proportional load current sense
■ Shorted load protection
■ Under-voltage and over-voltage shutdown
■ Over-voltage clamp
■ Thermal shutdown
■ Current limitation
■ Protection against loss of ground and loss of VCC
■ Very low standby power dissipation
■ Reverse battery protected (see Application schematic)
