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. OVP/UVP (OverVoltage/Un.
