The STM6822RWY6F is a specialized Power Management Integrated Circuit (PMIC)—also known as a Supervisor—that designed for efficient voltage control and monitoring for low wattage circuits. This PMIC, which was developed by STMicroelectronics, is targeted for integration into small devices powered by a coin-cell battery, and other applications where a long running time is desired.

The STM6822RWY6F serves as the main power controller in battery-powered devices. It integrates necessary elements for efficient power and current management, as well as for preventing the device from malfunctioning. This PMIC supervises the battery voltage and input voltage, to ensure that the device’s integrity is not compromised by under- or over-voltage. It also has adjustable under-voltage lockout and charging thresholds, both of which can be adjusted to accommodate a wide range of battery chemistries. The device also integrates an adjustable precision current limit to help protect the battery and system from over-charge and over-discharge, as well as several system configurations intended to support low power idle mode applications.

The STM6822RWY6F is made up of a system reset block, a reset timer block, a power management block and a voltage regulator. The system reset block monitors the battery voltage and performs an under-voltage lock-out feature that prevents the system from being powered-up until the input voltage is above the determined threshold. The reset timer block is designed to generate a series of reset signals for resetting the system when required. The power management block is used for power management and shutdown of the entire device when input or battery voltage is below the threshold. Finally, the voltage regulator is used to accurately regulate the system voltage when input voltage varies.

The STM6822RWY6F is a versatile PMIC that can be applied to a wide range of small power applications. Its precise voltage monitoring and control features make it a great option for battery-powered application, offering precise protection while also putting a priority on preserving the battery’s charge. Furthermore, its adjustable thresholds and current limit can be adjusted to fit a variety of different battery chemistries, offering a great degree of flexibility to the user. The STM6822RWY6F is an ideal option for anyone looking for a reliable PMIC for battery-powered applications.
