PMIC, or Power Management ICs, are integrated circuits that are used to regulate and provide power flows in electronic products. The ADM802MARN is a popular PMIC supervisor, which is often used to provide power control and monitoring within a system. This article will discuss the application fields and operating principles of the ADM802MARN supervisor.

The primary application field for the ADM802MARN is controlling and monitoring power within system-on-chips (SOCs). This PMIC supervisor is designed for use with SOCs that are powered by 3.3V or 5V DC sources and have a range of different power requirements. The ADM802MARN is also used in a wide range of industrial, commercial, and consumer electronic products, including computers, tablets, mobile phones, automotive systems, and home appliances.

The ADM802MARN is an integrated supervisor IC that monitors multiple voltage sources, providing power on/off control, power-up/brown-out protection, power-saving features, and open-drain/push-pull outputs. The device features a voltage monitor, reset timers, and a power-on reset circuit, which can be used to protect against accidental system resets and ensure that the power output is stable during system start-up and shutdown.

The ADM802MARN contains five primary components – a bandgap reference, an undervoltage reset circuit, an adjustable reset threshold, a power-on reset circuit, and an output latch. The bandgap reference is used to provide accuracy and stability in the device, while the undervoltage reset circuit is used to reset the device in situations where the power supply falls below the reset threshold. The adjustable reset threshold allows the user to set the desired reset threshold depending upon the system requirements, while the power-on reset circuit ensures that the device is initialized correctly upon start-up. Finally, the output latch is used to control the overall power status of the system.

The ADM802MARN supervisor is designed to be used in applications that require reliable power control and monitoring. The device is able to accurately monitor multiple voltage sources and provides robust protection features, ensuring that the system remains safe, secure, and operational. Additionally, the device is able to provide power saving features and open-drain/push-pull outputs, allowing it to be effectively used in low-power, low-voltage systems.

Overall, the ADM802MARN supervisor is an effective and reliable solution for systems that require robust power control and monitoring. The device is capable of monitoring multiple voltage sources, providing power-on protection, and implementing power saving features, ensuring that the system is always reliable, secure, and operational. The device is suitable for use in a range of different applications, making it a popular choice among engineers and designers.
