Introduction

The XC6123D721ER-G is a supervisor IC from Xilinx and is part of their PMIC (power management integrated circuit) family. Supervisors are special devices that monitor power supply and reset sequences in electronic equipment. As an example, this IC can be used to prevent system components from suffering irregular power-up or power-down cycles.The XC6123D721ER-G IC integrates many features that are necessary for successful supervisor applications. These features include voltage monitoring, reset generation, and power-on & power-down reset sequencing. In addition, it is designed to support up to 5 output signals.

Application Field

The XC6123D721ER-G IC can be used in a wide variety of applications. It is suitable for use in computer mainboards, portable electronics, communications equipment, and consumer products. In addition, it can also be used in automotive systems, industrial control systems, and in any application where power regulation and reset functions are required. Due to its low-power consumption, small form factor, and integrated features, the IC is ideal for power-constrained applications. It is also suitable for applications that require complex reset sequencing, such as those found in communications equipment.

Working Principle

The XC6123D741ER-G IC has three main functions- voltage monitoring, reset generation, and power-on & power-down reset sequencing.For voltage monitoring, the IC has two voltage inputs and an internal voltage reference. When the two voltage inputs exceed the reference voltage, the IC generates a group of reset signals. The reset signals are active high and can be used to reset other components in the system, such as microcontrollers, memories, and semiconductor switches.For power-on & power-down reset sequencing, the IC can generate multiple reset signals in a prescribed sequence to ensure that all components in the system properly enter their respective power states. Additionally, the IC has provisions for different power-on delay times as well as configurable reset filters to ensure that signals are not unintentionally reset.

Conclusion

The XC6123D721ER-G IC is an integrated PMIC (power management integrated circuit) designed for applications where voltage monitoring, reset generation, and power-on & power-down reset sequencing are required. It is suitable for applications such as computer mainboards, portable electronics, communications equipment, consumer products, automotive systems, and industrial control systems. The IC has two voltage inputs and an internal voltage reference, as well as provisions for configurable reset filters and power-on delay times. The reset signals are active high and can be used to reset other components in the system.
