PMIC – Supervisors are an important component of power management integrated circuits (PMIC), which are used in systems and devices that need to be off or in reduced-power modes. PMICs are usually found in portable electronic devices, such as smartphones and wearable technology. Supervisors are used to monitor the system\'s power sources, to ensure that the correct power levels are maintained, and to quickly shut down the system in the event of any suspected faults or abnormalities. The SR2UABU application field and working principle is one such example of a supervisor.

SR2UABU is a supervisor that is designed for a low power environment, such as a battery-powered mobile device. It is a 5V, 10 nA (nano-amp) supervisor that includes an over-current and reverse current protection circuit built in. This allows it to detect power supply abnormalities, like over-voltage, under-voltage, and reverse current. When a fault is detected, it will quickly shut down the power or reduce the voltage, to avoid damage to the system. SR2UABU also supports wake-up functions from a low power state, enabling better system start up times. It also supports hot-swapping (or mid-power) of power sources, which is useful for battery-powered systems.

SR2UABU also offers a one-wire interface for communication with the system. This allows for efficient, fast communication between the power source and the connected device. This interface also facilitates monitoring and triggering of system reset signals from external sources, such as a software program or hardware trigger. For example, a software program might trigger a reset signal when the system reaches a certain temperature, ensuring that the system is quickly brought back to a safe operating temperature.

SR2UABU includes a range of built-in features that make it a great choice for use in power management systems. It offers a low power consumption of 10 nA, making it an ideal choice for battery-powered systems. Its onboard protection circuits make it perfect for protecting the system from unexpected power faults. Its one-wire interface makes communication with the system simple, and its support for wake-up and hot-swapping makes it a great choice for quickly responding to changing power requirements.

In summary, SR2UABU is a great choice for systems that require low power and advanced system protection. Its onboard protection circuits and one-wire interface provide quick response times and make it ideal for battery-powered applications. Its low power consumption make it a great choice for conserving power, and its support for wake-up and hot-swapping make it perfect for quickly responding to changing power requirements.
