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.
Two Independent Enable Inputs (3.3 V Logic Compatible) - Save battery life - quiescent current down to 10µA max.
Adjustable Current Limits: up to 350 mA - Current sense feature provides diagnosis and system protection functionality.
Short to Battery and Open Load detection in OFF State
Internal Components for OFF State Diagnostics
Open Collector Flag Output - Provide diagnosis and system protection functionality.
Reduced Inrush Current (current value set by external resistor only) - Low startup current and no CSO capacitor.
Reverse Input Voltage and Reverse Bias Voltage
Reduced Reverse Bias Current - No diode protection needed
Output Current per Channel: up to 250 mA
