PMIC (Power Management Integrated Circuits) are widely-used circuits designed to manage the power needs of a device. Supervisors, a common type of PMIC, are responsible for constantly monitoring the status of a device and preventing potential problems as well as providing additional safeguards for power-related hazards. ADM802MARN-REEL is a specific supervisor from the Analog Devices, Inc. (ADI) family of PMICs, and this article will go into detail regarding its applications field and working principle.

The ADM802MARN-REEL is tailored for systems that use x86 processors and can monitor up to two power inputs. It offers a wide range of detection and control features, as well as an adjustable reset delay, all of which can be used to provide improved fault coverage and robustness in powering a device. Additionally, ADM802MARN-REEL has the ability to detect other violations, such as brown-out, power sequencing, and over-voltage events.A set of four supervisory inputs, selected by the user, can be used to detect any power-related or operational problem and generate an appropriate reset or interrupt.

The ADM802MARN-REEL also has two power sequencers for power sequencing and two power-supply monitor pins for monitoring power and/or supply voltages. The sequencers allow the user to determine when to turn on or off a power supply line, and the monitor pins can be used to detect any errors in the line voltage. The device can also be used to generate a reset upon any of these input signals, allowing the user to tailor the device for their specific application.

The key feature of the ADM802MARN-REEL supervisor is its ability to detect and shut down an incorrect input during a fault event. The device\'s fault response is set by the user with the Reset Delay setting, which can be adjusted from 0.5ms-500ms. This setting is important as a too-long delay could cause erratic system behavior or even a complete system crash, while a too-short delay could create further system instability due to the reset not being properly applied.

The ADM802MARN-REEL supervisor is ideal for applications such as microcontrollers, PC motherboards, single-board computers, servers, and embedded systems where the power management needs to be bar-none reliable. Adequate fault-coverage is provided by the adjustable reset delay and the fault-fill and power sequencing inputs, providing the user with an extremely reliable system power management solution that is tailored for their specific application.

The ADM802MARN-REEL supervisor also provides a range of control features, such as power sequencing, system-shutdown time indications, and supply fault flagging. Additionally, the device is capable of operating in a wide range of temperatures, making it suitable for both ambient and extreme temperature environments. Furthermore, the supervisor also features protection against over-voltage and under-voltage scenarios and can be used to detect power supply ripple and brown-outs.

In summary, the ADM802MARN-REEL supervisor from ADI is a highly reliable and effective solution for power management in x86 processor-based applications. The adjustable reset delay and fault-fill and power sequencing inputs provide excellent fault coverage and protection for the system being powered, while the control features and wide temperature range make it suitable for a wide range of applications. With so many features, the ADM802MARN-REEL supervisor is an ideal pick for nearly any system that needs reliable and robust power management.
