Power management integrated circuit (PMIC) supervisors are an important part of any automated system. PMIC supervisors such as the MN13822SQP are designed to maintain system stability and reliability by monitoring a variety of analog and digital signals. The MN13822SQP is an ultra low-power, computer-on-chip (CoC) based PMIC supervisor that is capable of supporting a wide range of applications. This article will provide an overview of the MN13822SQP’s applications and explain the underlying principles of its operation.

The MN13822SQP is capable of supporting a wide variety of applications due to its integrated supervisory and protection features. It has an integrated "Keep Alive" timer and watchdog timer that can be used to detect runaway code or system reset failure. Additionally, it is capable of monitoring the operating temperature of the system, detecting and responding to "brown-out" (inadequate voltage) conditions, and providing an interrupt when power is lost or restored. The MN13822SQP can also monitor the voltage on either one or two power rails, and can be configured to trigger an interrupt when a voltage falls outside of a predetermined range.

In addition to its supervisory and protection features, the MN13822SQP also supports a wide range of system fault diagnostics. It can be configured to detect faults such as over temperature, over voltage, under voltage, and open load conditions. It can also be used to detect and log power supply and system faults and send an interrupt to alert system administrators of potential problems. Furthermore, the MN13822SQP supports system power monitoring and can be used to provide a low-power indication to the user when the system is idle.

The working principle behind the MN13822SQP PMIC supervisor is based on voltage monitoring. Its integrated supervisory and protection circuitry is designed to detect and respond to abnormal conditions in the system, such as overcurrent, open load, and sudden voltage changes. The MN13822SQP monitors up to two power rails, and when a voltage is detected outside of a predetermined range, it sends an interrupt signal to alert the system of a potential issue. It also detects and logs power supply and system faults and can be used to prioritize power-down operations in cases of extended power supply disruptions.

The MN13822SQP has a wide range of features and applications, making it an ideal choice for any automated system. It has protective features that can detect and respond to a variety of faults, as well as diagnostic features that can monitor system faults and send an interrupt to alert system administrators of potential issues. Additionally, its low-power requirement and integrated supervisory circuit make it an ideal choice for computer-on-chip based applications.
