NCV47823
Dual High Side Switch with
Adjustable Constant Current
and Diagnostic Features
The NCV47823 is designed for using in harsh automotive
environments providing dual mode operation depending on the load
impedance: High Side Switch (HSS) or Constant Current Source
(CCS). In both modes of operation the current limit can be set up to
350 mA per channel by external resistor. 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 for each
channel) provides diagnosis and system protection functionality. The
CSO pin output current creates voltage drop across CSO resistor which
is proportional to output current of each channel. Extended diagnostic
features in OFF state are also available and controlled by dedicated
input and output pins.
