Introduction

The MAX6855UK32D2+T is an advanced power management integrated circuit (PMIC) from Maxim Integrated. It is part of a family of PMICs in the Supervisory section, offering features such as an integrated internal temperature sensor, reset output, and low-power supervisor for microcontrollers. The MAX6855UK32D2+T is ideal for a wide variety of applications, from consumer electronics and computers to industrial and automotive systems.

Application Field

The MAX6855UK32D2+T is a highly-integrated power management device that combines a low-power supervisor, reset output, temperature sensor, and other essential IC components into a single package. It is designed for applications requiring efficient power supply management. The device is ideal for any system that needs to monitor multiple power sources and/or maintain an operating voltage. It is well suited to be used in battery-powered systems, as well as in industrial, automotive, and consumer applications. It can also be used in applications requiring internal temperature sensing.

Working Principle

The MAX6855UK32D2+T has a comprehensive set of features that enable it to efficiently manage power supply operations. In particular, it has an integrated internal temperature sensor, reset output, reset monitor, and low-power supervisor. The internal temperature monitor allows the MAX6855UK32D2+T to detect temperature changes and respond accordingly. It can be programmed to put the system into stand-by mode, initiate a restart, or shutdown operations when temperature reaches specified thresholds. Additionally, the device can be used to detect over-voltage and under-voltage conditions.The reset output allows the user to reset the supply voltage. When the voltage exceeds a predefined threshold, the device can reset the output voltage. This prevents the system from entering an unstable state, and ensures smooth operation.The low-power supervisor allows the user to monitor the condition of the power supply and detect power abnormalities. In the event of a power outage, the MAX6855UK32D2+T can initiate a restart sequence and ensure that the system remains operational.The MAX6855UK32D2+T also has an integrated reset monitor. This allows the user to monitor the reset signal, and detect failures before they occur. The device can be programmed to send an interrupt signal if the reset signal fails and help the system stay in a safe operational state.

Conclusion

The MAX6855UK32D2+T is an advanced power management integrated circuit from Maxim Integrated. It is an ideal solution for applications requiring efficient power supply management. Its integrated temperature sensor, reset output, reset monitor, and low-power supervisor make it well-suited for use in a variety of applications, including battery-powered systems, industrial, automotive, and consumer applications. The device offers a comprehensive set of features that enable it to effectively manage power supply operations.
