Working Principle

The XC6121D740MR-G is a multi-function supervisory IC for system power management. It monitors system power in order to protect the system from over-voltage, under-voltage, and over-temperature conditions. It also provides system reset and PSON signal generation.The XC6121D740MR-G works by monitoring its internal and external input conditions. For example, it monitors input voltages to ensure they stay within specified ranges, and it monitors the temperature of the board to ensure it remains within specified limits. If any of the input conditions become out of range, the XC6121D740MR-G will assert a PSON (Power-ON) signal to the power supply in order to reset the system. Additionally, it can generate a system reset to prevent any further damage to the system. The XC6121D740MR-G is highly customizable, as it can be programmed to support various reset thresholds and timing parameters, as well as various system power requirements. It is designed to be easily adapted to different power supplies and system configurations, making it a versatile and cost-effective solution for system power management.

Conclusion

XC6121D740MR-G is a multi-function supervisory IC for system power management. It is designed to provide reliable and secure operation in a wide range of applications. Its wide operating temperature range and its on-chip monitoring functions make it ideal for industrial and automotive applications. Additionally, it can be used in PC systems and mobile system boards, networking/telecommunication equipment, and consumer/home entertainment products. The XC6121D740MR-G works by monitoring its internal and external input conditions and performing reset functions when necessary.
