PMIC - Supervisors

PMIC (Power Management IC) supervisors are widely used for system management and control purposes in many industries, particularly those requiring high voltage protection. The MAX6388XS29D2-T is a subminiature 3.2V manual reset supervisor from Maxim Integrated. This application note describes the application field and working principle of the MAX6388XS29D2-T.

Application field

The MAX6388XS29D2-T is applied to watch a circuit’s main power supply voltage. It serves as an important device for protecting against overvoltage and undervoltage conditions. This supervisor is especially suitable for power-supplied applications, especially in fields where low power consumption and small size are desired.

The MAX6388XS29D2-T is designed to watch the power supply voltage of the main circuit while it is operating. It can detect any level of overvoltage or undervoltage and then perform the necessary action to restore the normal power supply voltage.

The MAX6388XS29D2-T also serves as a system supervisor for many various electronic components and assemblies. This includes providing voltage monitoring for LCD screens, CPUs, FPGAs, system memory chips, and more, as well as controlling the temperature of the system’s fan in order to keep the device from overheating.

Working Principle

The MAX6388XS29D2-T is a manual reset supervisor designed to protect the main circuit voltage from overvoltage and undervoltage conditions. It has two main inputs: the main voltage detection pin and the manual reset pin.

When the main voltage detection pin detects an overvoltage or undervoltage, the supervisor’s output will switch to active mode and will remain in this mode until either the voltage is restored to its normal operating range or the manual reset pin is pulled.

The MAX6388XS29D2-T can operate very accurately to maintain the voltage within the specified range. It has an accuracy of ±2.5% of the set voltage, and can detect any voltage change over a time period of 8μs.

In addition, the MAX6388XS29D2-T has an adjustable current limit and can withstand up to 500mA of current, making it suitable for a wide range of applications.

Conclusion

The MAX6388XS29D2-T is a 3.2V manual reset supervisor from Maxim Integrated, designed to protect a main circuit voltage from overvoltage and undervoltage conditions. It is suitable for a wide range of applications due to its adjustable current limit, accuracy, and its ability to detect any voltage change in an 8μs period.
