Features

The NCV47722 High Side Switch (HSS) with 250 mA is designed for use in harsh automotive environments. The device has a high peak input voltage tolerance and reverse input voltage, reverse bias, overcurrent and overtemperature protections. The integrated current sense feature (adjustable by resistor connected to CSO pin) provides diagnosis and system protection functionality. The CSO pin output current creates voltage drop across CSO resistor which is proportional to output current. Extended diagnostic features in OFF state are also available and controlled by dedicated input and output pins.
