2U3823-30QDBVRG4Q1

PMIC - Supervisors

The 2U3823-30QDBVRG4Q1 is a type of PMIC, or Power Management Integrated Circuits, supervisors. It is designed to help stabilise DC power supplies and sutable for use with a 6V-24V DC power source. The device is capable of providing, in a single package, low-voltage level detection, switchover between power sources, and reset functions.

Application Field and Working Principle

The applications of the 2U3823-30QDBVRG4Q1 include reset functions for systems as well as true and rest power-supply functions, battery management, low-voltage level monitoring, switchover between AC and DC, and more. By using this device, switching between AC and DC power sources can be managed automatically, with minimum losses due to switching delays.

The 2U3823-30QDBVRG4Q1 is a single package dual-channel device. Each channel contains an independent high-accuracy voltage detector, that provides programmable voltage threshold control, as well as a comparator and buffer circuit. This allows the switching action of the device to respond almost immediately to changes in the input power. In addition, the device also features a manual reset input and a timeout function, giving users the flexibility to choose when the reset will occur and how often it will be repeated.

The device is also equipped with an undervoltage lockout (UVLO) and thermal shutdown circuit, which helps to protect the device from short-term overvoltages, undervoltages and thermal overloads. The UVLO circuit operates when the input voltage is below the UVLO level, and shuts off the device until the voltage rises above the threshold, thus preventing any damage to the device from overuse or incorrect voltage levels.

The 2U3823-30QDBVRG4Q1 is easy to interface with a microcontroller or processor through standard I2C and SPI interface, which supports read/write operations, enabling the device to communicate directly with its operating system. In addition, the 2U3823-30QDBVRG4Q1 has a wide range of operating temperature ranges, from -40°C to +125°C.

The 2U3823-30QDBVRG4Q1 is widely used in applications where power stability and safety is a must, such as factories, energy systems, and other industrial settings. It is a reliable and cost-effective solution, and a great way to ensure the reliability and safety of any system.
