onsemi NCP112
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.| Part No. | NCP112 |
