Power Management ICs, or PMICs, are very important components in electronic system design. They are responsible for controlling the power and energy delivery from the power supply to the various devices within the system. One type of PMICs is Supervisors, which are used to detect and control power management events. The ADM825MYRJ-R7 is an example of a Supervisor IC. This article will explain the application field and working principle of the ADM825MYRJ-R7.

Application Field of ADM825MYRJ-R7

The ADM825MYRJ-R7 is suitable for applications that require protection of the system or individual components against power faults, such as over-current, over-voltage and under-voltage. Such applications include computer workstations, Internet of Things (IoT) and industrial systems. It combines features such as manual reset and open drain output, which make it easy to use in various settings. Additionally, the IC is well-suited for low voltage operations, making it suitable for a variety of applications.

Working Principle of ADM825MYRJ-R7

The ADM825MYRJ-R7 is a supervisor IC, which has the function of monitoring voltage levels. It is composed of multiple inputs, such as the power input, reset input and manual reset input. When the power supply range moves out its prescribed voltage range, the IC will output an active low signal. This active low signal is then connected to a reset controller, which can reset the system or individual components. It also has an open drain output, which can be used to drive an external device or other circuit.

The ADM825MYRJ-R7 also has a manual reset input, which can be used to force a system or device reset. This input accepts a high level until it is pressed, which forces the reset output to a low level. Additionally, the IC supports a hysteresis function to ensure that the output is not constantly switching states when the voltage is near the threshold level.

In addition to its power management capabilities, the ADM825MYRJ-R7 also includes an embedded temperature sensor. This sensor helps to detect temperature levels, so that the IC can be programmed to perform specific functions, such as limiting the system’s current or preventing an over-temperature event.

The ADM825MYRJ-R7 also features a dedicated active-low reset pin that is used when the reset output is enabled. This pin provides an active-low voltage level to the reset controller, allowing the system to be reset without any additional control circuitry.

Conclusion

The ADM825MYRJ-R7 is a Supervisor IC designed for use in applications requiring power management or protection. It has an onboard temperature sensor and outputs an active-low signal to the reset controller when the power supply exceeds its specified limits. It also has a manual reset input and open drain output, making it easy to use in various applications. This article has presented the application field and working principles of the ADM825MYRJ-R7.
