NCV47821: 3.3 V to 20 V Adjustable Dual LDO with Adjustable Current Limit and Diagnostic Features

Description: The NCV47821 dual channel LDO regulator with 200 m...
  • The NCV47821 dual channel LDO regulator with 200 mA per channel 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 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.
  • Features
  • Two Independent Enable Inputs (3.3 V Logic Compatible) - Save battery life - quiescent current down to 10µA max.
  • Adjustable Current Limits: up to 300 mA - Current sense feature provides diagnosis and system protection functionality.
  • Diagnostic Features: 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.
  • Adjustable Outputs: 3.3 V to 20 V ±3% Output Voltage
  • Output Current per Channel: up to 200 mA
  • Protection: Current Limitation, Thermal Shutdown, Reverse Input Voltage
