Overview

NCP4350 Supervisory IC for Desktop Power Supply Monitoring The NCP4350 provides all the necessary functions to monitor and control a multi-output power supply providing fault protection shutdown signals, and On/Off control.

The NCP4350 provides the ability to monitor the status of the +5 Vdc, +12 Vdc (A and B outputs), and +3.3 Vdc output (voltage and current).

The controller has built in delay to prevent tripping during transient conditions to eliminate false shutdowns.

Key Features

  • ăIndividual Overvoltage and Undervoltage Monitoring for +3.3ĂV, +5ĂV, +12ĂVA, +12ĂVB Outputs and Lockout.
  • ăIndividual Overcurrent Monitoring for +3.3ĂV, +5ĂV, +12ĂVA, +12ĂVB Outputs and Lockout.
  • ăFault Output with 5 mA of Sink Capability.
  • ăRemote On/Off.
  • ăPower Good Output Signal with 5 mA of Sink Capability.
  • ăBuilt-in Delays for OVP, UVP, and Overload to avoid False Tripping.
  • ăLow Power Consumption 10 mW at VCC = 5ĂV Typical.
  • ăOve.
