PMIC - Supervisors are integrated circuit (IC) families typically used in microprocessor or microcontroller-based applications. The NCP112P is a highly integrated system reset supervisor family developed by ON Semiconductor. It is designed for providing system reset functions for PC systems, industrial and communication equipment, and other applications. This article will discuss in detail the application field and working principle of the NCP112P.

Application Field

In terms of its application field, the NCP112P system reset supervisor family is mainly used for PC systems, industrial or communication equipment, and other applications.The NCP112P is used in PC systems such as personal computers, gaming platforms, servers, etc. It helps maintain system integrity by providing a reliable system reset. It is also used in a wide variety of industrial and communication applications. Applications include power supply, process control, medical equipment, digital signal processors, remote radio access base stations, fire and intrusion systems, industrial control networks, etc.

Working Principle

The working principle of the NCP112P system reset supervisor is actually quite simple. It is based on a single chip integrated circuit, which works by monitoring the V DD supply voltage for any sudden drops or spikes, and then initiating a system reset if the voltage falls below or rises above the specified limits. When the chip detects a sudden drop or spike in the supply voltage, it issues a reset pulse. This pulse can be either active-high, active-low, or open-drain and will hold the system in reset until the voltage returns to its normal operating range.The NCP112P also features a wide input voltage range, from 2.4V to 5.5V, with adjustable reset thresholds. This allows the device to be used in a wide variety of applications and ensures that it can reliably monitor and detect sudden drops or spikes in the supply voltage. The NCP112P also offers a wide range of additional features to further improve reliability and system integrity. These include a manual reset input, power-on reset, power-fail monitoring, timeout and watchdog timer reset functions, adjustable clock output, and much more. All these features combined make the NCP112P the ideal device for providing system reset functions in a wide variety of applications.

Conclusion

In conclusion, the NCP112P system reset supervisor family from ON Semiconductor is a highly integrated device that is designed for providing system reset functions for PC systems, industrial, and communication applications. It is based on a single chip integrated circuit that works by monitoring the V DD supply voltage for any sudden drops or spikes, and then initiating a system reset if the voltage falls below or rises above the specified limits. Its wide dynamic range, wide input voltage range, manual reset input, power-on reset, power-fail monitoring, timeout and watchdog timer reset functions, and additional features, makes the NCP112P an ideal choice for most applications.
