VN920-E Single-channel high side driver Features Type RDS(on) IOUT VCC VN920-E VN920-12-E 16 m 30 A 36 V PENTAWATT CMOS compatible input Proportional load current sense Shorted load protection Under voltage and overvoltage shutdown Overvoltage 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 on page 16) In compliance with the 2002/95/ec european directive Table 1. PENTAWATT in-line Description The VN920-E is a monolithic device designed in STMicroelectronics VIPowerTM 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 able). 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.
