NCP112 Datasheet Supervisory-ic

Manufacturer: onsemi

Overview: 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 municate it to the system controller. The programmable output delays protect against spurious fault indicators.
