VNQ500 Quad channel high-side driver Features Max supply voltage VCC 41V Operating voltage range VCC 5.5 to 36V Max on-state resistance RON 500m Current limitation (typ) ILIM 0.4A Off-state supply current IS 25 A PowerSSO-12 Description CMOS compatible I/O's Chip Enable Junction over temperature protection and diagnostic Current limitation Shorted load protection Undervoltage shutdown Protection against loss of ground Very low standby current In compliance with the 2002/95/EC european directive Table 1. The VNQ500 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 current limitation, combined with latched thermal shutdown, protect the device against overload. In the case of over temperature of one channel the relative I/O pin is pulled down. The device automatically turns off in the case of ground pin disconnection.
