Introduction

A PMIC (Power Management Integrated Circuit) - Supervisors is a type of electronic device designed to help manage and regulate the power supply, helping to ensure its proper functioning. It is usually used in conjunction with power sources such as batteries or AC adapters. The MAX708TCUA-T is a PMIC - Supervisors, which helps to provide a safe and stable operating environment for the connected source.

Application Field

The MAX708TCUA-T is commonly used to protect circuits from damage due to overvoltage, over current, and over-temperature. This device is often used for mission-critical applications such as industrial, medical, and automotive systems. It is designed to provide protection for devices that are working under extreme conditions, helping to ensure their safe and reliable operation.In addition, the MAX708TCUA-T is highly recommended for use in battery charger applications. This device, with its adjustable voltage threshold and two different current thresholds, is able to monitor and protect battery chargers from overvoltage, overcurrent, and over-temperature conditions. This ensures the safe and reliable operation of the battery charger and protects the battery from damage.

Working Principle

The MAX708TCUA-T is a Voltage Supervisor IC, which means it controls and monitors the voltage of the connected power source. It has a built-in voltage threshold sensing circuit, which monitors the voltage of the power source and compares it to its preset threshold value. If the voltage exceeds the threshold value, the device will enter "Latched Shut-down" mode (or "Key OFF" mode). In this mode, the device will disconnect itself from the power source, thus preventing any further damage.Apart from this, the MAX708TCUA-T also features two different current thresholds, which are used to monitor and control the current flowing through the connected power source. If the current exceeds any of these two thresholds, the device will also enter its "Latched Shut-down Mode", cutting off any further power flow. This helps to protect the device from overheating and other excessive conditions.

Conclusion

In summary, the MAX708TCUA-T is a PMIC - Supervisors designed to monitor, regulate and protect the connected power source. It has a built-in voltage threshold sensing circuit, two different current thresholds, and a "Latched Shut-down Mode", which all work together to protect the connected source from overvoltage, overcurrent, and over-temperature conditions. This makes it ideal for mission-critical applications such as industrial, medical, and automotive systems, as well as battery charger applications.
