Introduction to XC6121F626MR-G

XC6121F626MR-G is a low voltage supervisor with a reset output. It is a voltage supervisor with low current consumption, high accuracy and low power consumption from the XC6121 series of low voltage supervisors manufactured by Toshiba Semiconductor & Storage.XC6121F626MR-G is an enhanced version of XC6121F626-G, which adds an additional low-power cut-off (LP-Cut) function to better accommodate complicated system designs. The extra LP-Cut feature provides a separate control pin that can be used to control the power consumption of the system, eliminating the need for additional components. The XC6121F626MR-G features an internal detection threshold of 2.2V and an external detection threshold of 1.95V, with a voltage monitoring error of ±1%. It also uses an integrated power transistor for enhanced performance and longer life.

Application Field

XC6121F626MR-G is a highly accurate and reliable low voltage supervisor, capable of providing accurate detection of power-on, power-off and low voltage conditions for a wide range of applications. It can be used in a variety of applications to monitor and control the power supply, as well as to prevent system failures or malfunctions. This includes systems in automotive, industrial control, medical and consumer electronics.

Working Principle

XC6121F626MR-G uses differential sensing to accurately measure the supply voltage and detect various voltage conditions. It is capable of detecting voltages that are below, above or equal to the set threshold value. When the supply voltage falls below the (internal/external) detection threshold, the reset output is activated and the system is reset. The reset output is also triggered when the supply voltage rises above the (internal/external) detection threshold, or is equal to the set threshold value.The XC6121F626MR-G also features an integrated power transistor which is used to control the power consumption of the system. The LP-Cut feature can be used to reduce the power consumption of the system, eliminating the need for additional components.

Conclusion

XC6121F626MR-G is a highly accurate and reliable low voltage supervisor from the XC6121 series. It is a voltage supervisor with low current consumption, high accuracy and low power consumption, capable of providing accurate detection of power-on, power-off and low voltage conditions for a wide range of applications. The addition of the LP-Cut feature provides a separate control pin that can be used to reduce the power consumption of the system, eliminating the need for additional components. It is an ideal solution for systems in automotive, industrial control, medical and consumer electronics.
