NCV47722

High Side Switch with

Adjustable Current Limit and

Diagnostic 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.
