VN920SP Single channel high-side solid-state relay Features Type VN920SP RDS(on) IOUT VCC 15 mΩ 30 A 36 V 10 ) s ( t PowerSO-10 c u d o r Description P e t e l o s b -O 1 ■ 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 ) ) s ( ct u d o r P e t e l o s b O Table 1. The VN920SP is a monolithic device designed in STMicroelectronics VIPower M0-3 technology. The VN920SP 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. The device integrates an analog current sense output which delivers a current proportional to the load current. The device automatically turns off in the case where the ground pin becomes disconnected.
