Power management integrated circuits (PMIC) play a vital role in portable and embedded systems. Although traditionally ICs were used to manage discrete power rails, today’s PMICs are complex subsystems on-chip. This has been made easier, faster and more cost effective due to production and design advances in integration of numerous power, signal, and control functions. Supervisors, in particular, are used to maintain system stability by providing overvoltage, undervoltage and brownout protection.

XC6124A529MR-G is a supervisor in a small SOT-25 package optimized for consumer products with I2C communication interface and a built-in voltage boosting to support system reset. It provides on-chip voltage detection, power-on reset, push-pull reset output, watch-dog reset output, power gate reset for system restart, as well as adjustable reset-delay function for power supply output voltage monitoring. It performs quickly, accurately and reliably in consumer, industrial and portable products.

The XC6124A529MR-G application field is mainly in consumer, industrial and portable products. The features of XC6124A529MR-G allows it to be used in a wide range of applications such as embedded systems and power management system, computer motherboards, and handheld appliances. It also has built-in ESD protection and a wide operating temperature of -40℃ to +125℃ for hard working environments. The XC6124A529MR-G provides overvoltage protection, undervoltage protection, and brownout reset for smooth system startup and reliable system operations.

The working principle of XC6124A529MR-G is based on the overvoltage, undervoltage, and brownout protection circuits. When power is supplied, the XC6124A529MR-G will detect any overvoltage, undervoltage or brownout condition that may occur. If the voltage drops below the threshold, or rises above the threshold, the XC6124A529MR-G will provide an immediate reset signal. This reset signal is triggered by a built-in voltage boosting circuit which can deliver sufficient current to reset the system.

The XC6124A529MR-G has several features to help reduce system current consumption. It can detect overvoltage, undervoltage and brownout conditions without the need of an external reference voltage. It also offers integrated power-on reset output that allows for more reliable system startup. The adjustable reset delay ensures the system is powered up and ready before resetting. Additionally, the integrated watch-dog reset output allows for more reliable system operation.

In short, the XC6124A529MR-G Supervisors are renowned for their accurate detection of voltage conditions and reliable reset output. It provides superior system stabilization and works in a wide operating temperature range, making it suitable for a variety of applications including embedded systems, computer motherboards and handheld appliances. It is an ideal choice for power management and system reset.
