The VN920 is a single channel high-side solid-state relay. It 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 and reverse battery protection.
The VN920 is a monolithic device designed in STMicroelectronics VIPower MO-3 technology, intended for driving any type of load with one side connected to ground. It integrates an analog current sense output which delivers a current proportional to the load current.
The device includes comprehensive protection features such as shorted load protection, under-voltage and over-voltage shutdown, thermal shutdown, and active current limitation combined with automatic restart. It also protects against loss of ground and loss of Voc.
