Power management integrated circuits (PMICs) are devices that help manage power in an electronic system. They help regulate voltage, current, and temperature in order to maximize performance and efficiency. Supervisors are a type of PMIC used to help maintain system operation during start-up and when certain conditions are met. The MIC2772-T3T3BML-TR is a supervisor designed to provide protection to microprocessors, digital logic, processors, and integrated circuits. This article will discuss the various applications of the MIC2772-T3T3BML-TR as well as its working principles.

Applications

The MIC2772-T3T3BML-TR is well-suited for a range of applications. These include microprocessor systems such as Embedded PC, PC/104, PC/104+, EPIC, and PCMCIA applications. It is also used in industrial and consumer digital audio, digital video, telecommunications, consumer electronic power supplies, and automotive systems. Additionally, the MIC2772-T3T3BML-TR can be used in consumer systems such as notebook computers, cell phones, personal digital assistants, and portable navigation devices.

This device is also ideal for medical systems such as medical imaging, diagnostics, and monitoring systems. Furthermore, it is suitable for use in general-purpose control applications as well as data processing, portable test equipment, and military systems. Lastly, this device is designed to meet the requirements of various environmental conditions and regulatory standards such as RoHS and WEEE.

Working Principles

The MIC2772-T3T3BML-TR contains four monitoring components. These are a reset output, active-high reset, active-low reset, and voltage supervisor. It also includes an adjustable reset timeout feature and chip enable output. When the monitored inputs exceed the preset thresholds, the reset output will pull low and the voltage supervisor will trip, indicating a fault condition.

The active-high reset is used to initiate a system startup. It can be connected to a reset control input that is enabled by a processor during system developments. The active-low reset is triggered by a user-defined reset source and is used to reset a system during normal operation. It can also be used to initiate a secure boot sequence.

The voltage supervisor continuously monitors a wide range of voltages and will trigger a system reset if the voltage level exceeds a preset limit. This ensures that the system does not operate outside an acceptable range and can protect against soft program or hardware errors. The adjustable reset timeout feature allows the user to set a specific period after which the reset output will become inactive. It is used to prevent false signals from resetting the system.

Lastly, the chip enable output is used to enable other components in the system. It provides low active signals whenever any of the monitored voltages pass predetermined thresholds.

Conclusion

The MIC2772-T3T3BML-TR is a supervisor designed to provide protection to microprocessors, digital logic, processors, and integrated circuits. It is suitable for a range of applications, including microprocessor systems, industrial and consumer digital audio, medical systems, and general-purpose control applications. The MIC2772-T3T3BML-TR contains four monitoring components, an adjustable reset timeout feature, and a chip enable output. Together, these components help protect against system malfunctions and ensure maximum system performance and efficiency.
