Power management integrated circuit (PMIC) supervisors are a reliable, cost-effective solution for ensuring the proper operation of a system by monitoring its power and resetting it when necessary. The BD5223G-TR is a high-precision supervisor circuit from ROHM Semiconductor that can precisely monitor and control a wide range of voltages, providing greater power efficiency and reliability for applications requiring precision power management.

The BD5223G-TR provides a comprehensive power management solution for a variety of applications, such as industrial and consumer products, automotive systems, and other high-precision embedded control systems. It offers an integrated voltage reference, voltage detector, and low-power shutdown circuit, along with an adjustable threshold voltage. This allows the BD5223G-TR to precisely monitor and control multiple voltages simultaneously.

The BD5223G-TR offers two peak current ratings: 30mA and 3.2 mA. The 30mA peak current rating enables the BD5223G-TR to support a wide range of input voltage applications, while the 3.2mA peak current rating allows it to be used in applications where low-power operation is desired. This wide range of current ratings gives the BD5223G-TR a great deal of flexibility, making it suitable for a variety of power control applications.

The working principle of the BD5223G-TR is based on its internal voltage reference, voltage detector, and low-power shutdown circuit. When the voltage at its inputs exceed the internal reference voltage, the BD5223G-TR will shut down the system to protect against overvoltage conditions. It features an adjustable threshold voltage, which allows it to be precisely configured to monitor and control multiple voltages simultaneously.

The BD5223G-TR is also provided with a power-on reset (POR) circuit and a system reset (SR) circuit. The POR circuit monitors the voltage level of the system after power up and provides a reset signal when the voltage level is below the minimum reset level. The SR circuit monitors the voltage level of the system and provides a system reset signal when the voltage level drops below the preset value.

The BD5223G-TR is the ideal solution for applications requiring precision power management and protection against overvoltage and reset conditions. It offers excellent precision and reliability, as well as a wide range of current ratings and adjustable threshold voltage, making it suitable for a variety of power control applications.
