Datasheet Summary
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/UnderVoltage Protection) monitors 3.3ĂV, 5ĂV, and dual 12ĂV to protect the power supply, FPOB output goes high when one of these supply voltages exceed their limits.
OCP (OverCurrent Protection)...
