STMicroelectronics VN920SP Manuals

The VN920SP is a high-side single-channel solid-state relay with the following features: CMOS compatible input, proportional load current sense, shorted load protection, under-voltage and over-voltage shutdown, over-voltage clamp, thermal shutdown, current limiting, protection against loss of ground and loss of VCC, very low standby power dissipation, reverse battery protected.

The VN920SP is a monolithic device designed 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 sense output which delivers a current proportional to the load current. Device automatically turns off in case of ground pin disconnection.
