XC6121E626MR-G

Power management integrated circuit (PMIC) supervisors are a type of PMIC specifically designed to reset processor, RAM and I/O settings upon detection of power supply variations. The XC6121E626MR-G is one of the most popular such supervisors in the market, offering a wide range of features that enable it to provide robust protection against outside interference and unexpected environmental conditions.

Design

The XC6121E626MR-G PMIC supervisor is designed to be small, benefit from further integration with other ICs, and be easily adaptable to any system it\'s being used in. It has an operating voltage range of 2.0V to 6.5V, making it suitable for a wide range of applications. It also boasts a very low quiescent current of 4 μA, allowing for economical operation and efficient power monitoring.

Reset Functionality

The XC6121E626MR-G\'s reset functionality acts as a system safeguard to protect against unexpected problems or conditions. It is designed to detect voltage drops below the trip point threshold, giving the system time to shut down gracefully in the event of overvoltage or undervoltage. Furthermore, it features adjustable trip points and also programmable reset time delays. This can help protect systems that are located in hazardous locations or may experience unstable voltage conditions.

Processor Monitoring

The XC6121E626MR-G includes a monitoring feature that continually checks the state of the processor by watching the power supply voltage. It is able to provide a reset signal to the processor when the voltage drops below the designated trip point. This is an important feature for system reliability, as it helps accurately detect when the processor has stopped working or has been put into an invalid state.

I/O Protection

In addition to its processor monitoring capability, the XC6121E626MR-G is also capable of providing I/O protection. It has two built-in protection channels for I/O overvoltage and undervoltage. This helps protect system peripherals from unexpected voltage problems by regularly monitoring the power supply voltage and providing reset signals to the I/O whenever the voltage exceeds the designated trip point. This feature is essential in locations with unstable power supply conditions.

Applications

The XC6121E626MR-G is suitable for a wide range of applications, including computers, industrial systems, communications, automotive systems, and consumer electronics. Its wide range of features make it ideal for use in any application where system reliability is critical. The XC6121E626MR-G is especially popular in industrial applications, such as factory automation systems, since its reset functionality helps ensure system stability and reliability even in unstable environments. It is also widely used in automotive systems, such as powertrain systems and infotainment systems.

Conclusion

The XC6121E626MR-G PMIC supervisor is a powerful and feature rich device designed to provide robust protection against voltage fluctuations and voltage disturbances. It is designed to be small, easy to integrate with other ICs, and adaptable to any system it\'s used in. Its reset functionality, I/O protection, and power management capabilities make it extremely versatile and suitable for use in a wide range of industrial and consumer applications.
