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.
