Supervisory IC for Desktop

Power Supply Monitoring

The NCP112 is a highly integrated supervisory circuit that

incorporates all the functions necessary for monitoring and

controlling a multi−output switch−mode power supply system. The

NCP112 provides an ability to monitor the status of the power supply

outputs and communicate it to the system controller. The

programmable output delays protect against spurious fault

indicators.
