PMIC - Supervisors

The MN13822SLP is one of a variety of power management integrated circuit (PMIC) supervisors available from Panasonic. It is used in a wide array of electronic devices, including those that are connected to a variety of power sources for different purposes. Supervisors are especially useful in the protection of a device from damage due to excessive voltage, improper voltage sequencing and other hazardous conditions.

Application Field

The MN13822SLP is used in a variety of applications, including power regulation and management, voltage sequencing, power protectection and power supply monitoring. It can be used to ensure proper operation of any device when used in conjunction with other power management ICs. Power regulation and management is especially important for a wide array of electronic components and systems. Voltage sequencing is important for starting different components of a device in the correct order, and for controlling the flow of power to the various parts. Finally, power protection and monitoring are important to protect against hazardous conditions, including those caused by abnormal voltages, short circuits, current surges, and over-current conditions.

Working Principle

The MN13822SLP works in three distinct phases in order to provide superior power protection and monitoring. The first phase is a battery monitor. This component is used to monitor the battery level with a sense resistor. If the battery level reaches a preset value, the monitoring circuit will automatically disconnect the battery and then actively monitor the voltage levels of the remaining power sources. The second phase is the overvoltage protection circuitry. This component is used to detect when the input voltage has exceeded a preset value. When this occurs, the overvoltage protection circuit will automatically disconnect the input voltage source to prevent the device from further damage.

Finally, the MN13822SLP includes a temperature protection circuit. This component measures the temperature of the power source and disconnects it if the temperature exceeds a preset value. This can help protect the device from damage caused by excessive temperatures.

The MN13822SLP is a reliable, efficient, and cost-effective way to provide power management and monitoring. It offers superior protection and monitoring of the power sources in a variety of applications, and is an ideal choice for protecting a wide array of devices.
