NCP112
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.
