Power management integrated circuits (PMICs) are devices used to control the power of other components or systems. They usually provide voltage regulation and control of other power-related functions. PMICs are growing more and more popular due to their low price and wide availability. An example of PMIC is the NJU7701F44-TE1, which belongs to the PMIC - Supervisors category. This article will discuss the application field of this device and its working principle.

The NJU7701F44-TE1 is a supervisory PMIC designed for battery-operated products. It has a wide operating temperature range (-40℃ to +105℃) and features a high-accuracy low noise voltage detector circuit. The device monitors system power, and provides precise voltage monitoring with low power consumption and reset delay times adjustable via an external resistance. It also offers Watchdog timer, Power Failure signal and Support Voltage pin.

The NJU7701F44-TE1\'s main application is in Battery-powered systems. It can be used to monitor the voltage of the battery and control the system power accordingly. It is also used in data storage applications such as mobile phones, digital cameras and MP3 players. It is capable of controlling system voltage and providing over-temperature protection for these systems. In addition, the device is used in industrial applications such as automotive, military and medical.

The working principle of the NJU7701F44-TE1 is based on the principle of voltage regulation. When the input voltage varies, the device adjusts the output voltage to keep it within the specified range. The NJU7701F44-TE1 uses a combination of two regulators (Vcc and Vout) to achieves this. The Vcc regulator is used to set the internal voltage reference and the device adjusts the output voltage by comparing input voltage to the reference voltage. If the input voltage is higher than the reference, the output voltage will be reduced; if the input voltage is lower than the reference, the output voltage will be increased.

The NJU7701F44-TE1 also offers several additional features. It has a voltage monitor function that can detect when the input voltage drops below the threshold. When this happens, the device will issue a Power Failure signal to alert the system. It also has a Watchdog timer and a Support Voltage pin, which allows it to work with various types of power systems. Additionally, the device includes a precision temperature sensor with a range of -40℃ to +105℃, allowing it to monitor the system temperature and provide over-temperature protection.

In conclusion, the NJU7701F44-TE1 is a supervisory PMIC designed for battery-powered devices. It can be used to monitor the battery voltage, control system power and provide over-temperature protection. It also includes additional features such as a voltage monitor, Watchdog timer and Support Voltage Pin. The NJU7701F44-TE1 works by adjusting the output voltage to maintain it within the specified range. This makes it an ideal choice for battery-powered systems and data storage applications.
