PMIC Supervisors consist of multiple components which protect the power management devices from collapse due to various issues. The MAX16058ATA28+T is a supervisor that offers several high performance features such as wide supply range, high accuracy, integrated gate driver, SPI interface and adjustable latch-up protection. This application field and working principle will be discussed in this paper.

MAX16058ATA28+T Application Field

The MAX16058ATA28+T is a low-cost supervisor IC used in power management applications. This supervisor is suitable for use in both DC and AC power line protection applications. It can be used to protect the system power resources from damage or disruption due to low input voltage, over-current, or other voltage-related causes. It can also be used to directly monitor system temperatures and prevent overheating.

It is ideal for notebook computers, automotive, medical, industrial, aerospace, and telecom applications. It is available in two packages: one for single rail usage and one for dual rail usage. It offers a wide input voltage range of 4.5 V to 16.0 V, and a supply voltage range of 1.8 V to 5.6 V. It features an internal pull-up resistor, digital filter, and an adjustable reset threshold.

MAX16058ATA28+T Working Principle

The MAX16058ATA28+T works by monitoring the system voltage and controlling the state of the gate driver. It has an adjustable reset threshold which allows the user to specify the reset voltage and thereby determine the state at which the reset is triggered. The adjustable reset threshold also helps to prevent unwanted reset events, such as false alarms or when the voltage source drifts slowly or varying with multiple load conditions.

When the voltage reaches the specified reset threshold, the output signal is driven low, providing an indication that a reset is imminent. Depending on the application, the signal can then be used to trigger events such as a warning message, shut down the system, or simply allow the system to reset automatically. The signal can also be used to trigger a microcontroller or digital signal processor that can then execute the necessary actions.

The MAX16058ATA28+T supervisor also features an integrated gate driver that can provide up to 2.2 A of gate drive current. By providing sufficient gate drive current, the supervisor can ensure that all external power semiconductors are properly turned on/off. This helps to ensure maximum efficiency and extend the life of the power management semiconductor.

In addition, the MAX16058ATA28+T supervisor has an SPI interface that allows the user to easily configure various parameters such as reset threshold and delay time. This allows the supervisor to provide flexibility while still maintaining a user friendly, efficient control system.

Conclusion

The MAX16058ATA28+T supervisor is ideal for power management applications where system monitoring and controlling are required. It offers high performance and accuracy, and is suitable for use in a wide range of applications such as notebook computers, industrial, automotive, medical, and more. The adjustable reset threshold and integrated gate driver ensure that all semiconductors are properly turned on/off and that no false alarms take place. Additionally, the SPI interface provides flexibility and a user friendly, efficient control system. With its features, the MAX16058ATA28+T is a perfect choice for power management applications.
