Power management integrated circuits (PMICs) are devices that manage power supply and saving functionalities in portable and handheld devices. PMICs are designed to improve the overall performance and functionality of the device they provide power to while helping to reduce its power consumption. A specific type of PMIC, known as a supervisor IC or "supervisor," is responsible for resetting the power system and monitoring the power rails within it.

CAT809JTBI-GT3 is one such supervisor IC specifically designed for low-power applications. It is available in a small SOT-23-3 package and can deliver up to 6mA of active current and up to 400mA of standby current. Additionally, it features an internal voltage supervisor, allowing it to monitor up to three distinct voltage rails. This voltage monitoring feature supports both under- and over-voltage detection.

Because of its small size and low-power consumption, the CAT809JTBI-GT3 is well-suited for personal and portable devices like smartphones, tablets and wearables. Its capacity to support different voltage levels makes it perfectly suitable for small and medium embedded systems as well. Moreover, its low standby current consumption and ability to switch quickly among power rails make it suitable not only for short-term, but also for long-term application scenarios.

The CAT809JTBI-GT3 is designed to reset the system in case of a power failure, providing a reliable and secure system backup. In addition, its high-level supervision inputs can also detect power under- or overvoltage, resulting in a reset command to safeguard the system. It also includes separately adjustable rising and falling threshold ranges, as well as a power-on reset (POR) function, allowing users to configure the valve points for all voltages, reducing power consumption and increasing overall system reliability.

In sum, the CAT809JTBI-GT3 supervisor IC is a high-performance and low-power PMIC designed for use in low-power applications, such as wearable and embedded systems. It offers a range of features and functions that allow it to efficiently manage power, monitor voltage, and reset the device in the event of a power failure. With its small size, low power consumption, and robust features, it is an ideal choice for a wide range of applications.
