PMIC (Power Management Integrated Circuits) are a type of integrated circuit (IC) that combines several functions, such as controlling the flow of current, regulating the supply voltage, and safeguarding components from damage due to voltage and temperature fluctuations. Supervisors are one type of PMICs that are specifically designed to protect and monitor digital systems. The NCP301LSN25T1 is a Supervisory Circuit with Reset, Voltage/Temperature Supervision, and Watchdog Timer and is widely used for various applications.

The NCP301LSN25T1 is mainly used in applications such as computer disk drives, telecommunications, medical and home appliances. It has a wide operating voltage range of 2V to 25V, with a temperature range of -40°C to +125°C. It consists of a precision reset timer with 2 fixed timeouts, a reset output and a reset input, as well as voltage monitoring, temperature monitoring and watchdog timer.

Application Field

The NCP301LSN25T1 is widely used due to its wide operating voltage range and temperature range. It can operate from 2V to 25V and from -40°C to +125°C. It is suitable for use in industrial and consumer applications such as computer disk drives, telecommunications, medical and home appliances. The NCP301LSN25T1 can be used in various applications to provide reliable protection and monitoring of digital systems.

Working Principle

The NCP301LSN25T1 Supervisor Circuit has two outputs, a reset output and a reset input. The reset output is a low-level active RESET output. It goes low when the voltage or temperature falls below the programmed levels, or the watchdog timer times out. The reset output is used to reset the microcontroller when there is an error. The reset input is an open drain input which can be used to reset the supervisor after a timeout or voltage or temperature error.

The NCP301LSN25T1 also features a precision reset timer with 2 fixed timeouts, voltage monitoring and temperature monitoring. The precision reset timer monitors the system and handles timeouts by providing an active reset output when a timeout occurs. The voltage monitoring feature monitors the supply voltage and will go low if the voltage falls below the programmed level. The temperature monitoring feature will also go low if the temperature goes outside the programmed range. Finally, the watchdog timer can be used to detect errors in the system and will reset the system if an error is detected.

In summary, the NCP301LSN25T1 is a Supervisory Circuit with Reset, Voltage/Temperature Supervision, and Watchdog Timer. It is widely used for various applications due to its wide operating voltage range and temperature range. It is suitable for use in industrial and consumer applications such as computer disk drives, telecommunications, medical and home appliances. The NCP301LSN25T1 provides reliable protection and monitoring of digital systems with its precision reset timer, voltage monitoring, temperature monitoring, and watchdog timer.
