The XC6124F748MR-G is an energy-saving voltage supervisor integrated circuit, called a PMIC – Supervisors. It is used to monitor, maintain and regulate a power source or an input voltage on a system. Generally speaking, a voltage supervisor is a low power integrated circuit that monitors a system’s power supply or input voltage. It is used to provide advanced reset signals that are used to regulate and safeguard the system’s voltage integrity, prevent unexpected system reboot and other problems caused by insufficient power supply. The XC6124F748MR-G application field and working principle is a useful tool to better understand the functions of this device.

Application Field

To enhance system reliability and stability, the XC6124F748MR-G voltage supervisor can be used as guard rails which offer circuit protection to components with useful system reset features such as keeping track of a process’s voltage level, system reset timing and power line supply. The device features two voltage threshold options; single set at 4.75V and dual output set at 3.0V and 3.6V, making it suitable for Li-ion battery powered portable system designs as well as other various circuit types.

Once a voltage is detected falling outside the range or dropping below a certain threshold, the device will instantly generate a reset signal within its preset time delay. This reset signal may be used for various times within a circuit to restart the supply voltage, restore system operations and prevent the circuit from crashing. Additionally, XC6124F748MR-G devices come equipped with adjustable time delay options, enabling designers to optimize the reset time for various different application fields.

Working Principle

The XC6124F748MR-G voltage supervisor operates through its voltage comparison system, in which the device will compare a reference voltage (VREF) to its supply voltage (VIN). When VIN has dropped below VREF, the device will immediately start its reset process in order to restore the power within its preset time delay, achieving the desired reset characteristics. This operation will be the same regardless of when VIN exceeds VREF, allowing the device to perform its reset process even during low power operations.

In addition to this, the XC6124F748MR-G also includes advanced reset flags as well as a power supply voltage monitor/reset flag. The power supply voltage monitor/reset flag is used to detect any power supply voltage drops in order to prevent any unexpected system reboots. The flags may also be pre-programmed to use multiple reset times if necessary for a particular application. This makes the device even more versatile and reliable for a variety of different applications.

Summary

In conclusion, the XC6124F748MR-G voltage supervisor PMIC is an ideal choice for a variety of applications. It is a reliable and efficient device that is used to monitor, maintain and regulate a power source or input voltage on a system. Its dual voltage threshold options, adjustable time delay, power supply voltage monitor/reset flag and reset flags make it suitable for a wide range of applications, allowing designers to customize the device to meet their exact requirements.
