PMIC - Supervisors

PMIC (Power Management Integrated Circuits) is a class of integrated circuits that contain several pre-packaged electricity management functions on a single integrated circuit. The PMIC supervises integrated circuits are special ICs specifically designed to monitor power supplies and are ideal for resetting, powering down and powering up a system in the case of power outages and other events. This article will focus on the application field and working principles of the PT7M6135NLTA3EX, which is an example of a PMIC supervisor.

Application Field

The PT7M6135NLTA3EX supervisor IC can be used in a variety of applications. It is specifically designed for use in PCs and other electronic systems where reset control of multiple functions is necessary. The IC is primarily used in the monitoring of the primary and backup power supplies of the system and provides reset and power down when needed. The supervisory IC is perfect for providing additional safety against unexpected loss of power and allows for quicker recovery from system lockups and crashes.

Working Principles

The PT7M6135NLTA3EX supervisor IC is a high accuracy single-chip solution for monitor power supplies in electronic systems. It uses a voltage supervisor circuit to detect when there is a decrease in the primary supply voltage below its preset value. When the voltage drops, it triggers an immediate reset of the system to a safe level after the supply is restored. The monitoring circuit works using a comparator that is set to a factory preset threshold voltage of 4.63V. The IC also has debounce and fault reset times to help further protect the system from power outage and restart issues.

The first two features of this supervisor IC make it stand out from the competition. The active power-down mode allows the system to be quickly powered down if the voltage of the primary supply is too low, while the active reset allows the system to reset itself without requiring any user intervention. Additionally, the IC can be programmed to monitor and control up to four different power rails using independent monitoring inputs, providing greater overall control of power supply management.

This supervisor IC also has an advanced feature such as an interrupt output that can be used to communicate with other integrated circuits. The reset output can be used to reset the entire system or just a single integrated circuit, depending on the situation. Additionally, there is a wide range of timer functions including timer reset, watchdog, run-stop and interval counter, making this IC very versatile for a variety of applications.

Conclusion

The PT7M6135NLTA3EX supervisor IC is well-suited for use in PCs, servers, and other electronic systems as a primary or backup power supervisor. Its features include active power-down, active reset, and up to four independent monitoring inputs to provide greater control over the system\'s power supply management. Additionally, the supervisor IC has an interrupt and reset outputs, a wide range of timer functions, and an accurate voltage monitoring comparator to further ensure the safety of the system against unexpected loss of power. Overall, the PT7M6135NLTA3EX is an excellent supervisor IC for any system requiring power supply management.
