Power management integrated circuits (PMICs) are unique and versatile integrated circuits (ICs) that can be employed in a variety of applications ranging from portable consumer electronics to automotive, industrial, computer and communication systems. They are typically small, complex, and feature-rich integrated systems that combine multiple power supply, control, and protection functions into a small number of ICs. Supervisors are one of the most important types of PMICs. They are used to monitor vital parameters such as supply voltage, enable errors or faults, and trip a reset signal in the event of an over current, over voltage, overtemperature, etc. The XC6122C229MG-G is a popular supervisor IC that is often used in various applications.

The XC6122C229MG-G is a dual-channel voltage supervisor IC designed for applications where an accuracy of ±1% is required. It has a built-in reference voltage of 2.5V and an output voltage selection range of 1.6V to 5.5V. The IC also supports an adjustable time delay function that can be adjusted from 2.2ms to 3s. The IC operates from a single 3.3V to 5.5V power supply and is extremely power efficient with a quiescent current of 5 μA and a maximum operating current of about 500 μA. It also features a thermal shutdown and over-current protection, making it suitable for applications in the automotive and industrial sectors.

The XC6122C229MG-G operates in two different modes, which are active and standby. In the active mode, the IC enables power and monitors the supply voltage. If the supply voltage drops below the set level, the IC trips a reset signal and can reset a system microcontroller. In the standby mode, the IC maintains power while providing an adjustable time delay, allowing the system to gracefully enter sleep mode.

In addition to the voltage regulation and reset circuitry, the XC6122C229MG-G also has an extensive set of input monitoring functions. It has overcurrent protection that provides the user with an interrupt signal when the current exceeds a preset threshold. It also supports an adjustable temperature monitor and short-circuit protection. The combined protection and monitoring functions of the XC6122C229MG-G make it an ideal choice for applications in cars, computer systems, communication systems and portable consumer electronics.

The XC6122C229MG-G can be used in a wide range of applications where accurate voltage regulation and vital parameter monitoring is required. Its small size, low power consumption, and integrated protection features make it a great choice for applications in which space is limited. It is also an ideal choice for applications in consumer electronics, automotive, and industrial sectors.
