XC6121A221MG-G is a PMIC supervisor series, it integrates multiple PMIC functions and is mainly used as a power management solution. XC6121A221MG-G includes several main features, such as voltage ranges, voltage supervisory input, reset release, low quiescent current consumption, and several other functions. In this article, we will discuss the applications and working principles of XC6121A221MG-G.

Applications

XC6121A221MG-G can be used to provide power management solutions in a variety of products, including mobile terminals, portable consumer devices, home appliances, automotive electronics, industrial automation and computer systems. This PMIC series is specifically designed to provide the best solution to maximize system performance and to optimize power consumption while ensuring safe system power sequencing. It features a low quiescent current consumption, low voltage operating ranges and integrated voltage supervisory input.

XC6121A221MG-G also features a reset output that can be used as an external reset signal for systems such as CPUs or system power supplies. It also has an adjustable reset release time setting, which is a customizable feature for specific needs in different applications. In mobile terminal applications, these PMICs can be used to protect the host processor by providing a power-on reset signal, which will help ensure the safe operation of the processor and avoid random system failures. In addition, it can also monitor the switching power supply, providing a timely reset signal when the output voltage exceeds the range preset.

XC6121A221MG-G can also be applied in industrial automation, where it can provide a reset signal for microcontrollers or counters in order to pass data between the controlled device and the control unit. Finally, this PMIC series can be used in automotive electronics applications to provide reset and power supply control for power amplifiers or load control systems.

Working Principle

XC6121A221MG-G can detect changes in the power supply system across two channels of a comparator, one channel is connected to an adjustable reference voltage while the other one is connected to the regulated power supply. If the voltage detected by this voltage supervisor exceeds the preset range, the PMIC will detect this change, activate the reset output and send out a reset signal to prevent system errors from occurring.

When the voltage returns to the normal range, the reset output will be released after a certain delay, which is adjustable according to specific needs in different applications. The XC6121A221MG-G can also detect whether the power supply is maintained within the preset voltage level for a given time. If the voltage drops or is maintained at a low level for a too long period, then a reset signal will be generated to avoid system errors from occurring.

XC6121A221MG-G can also be used to control the power supply of microcontrollers and counters in industrial automation. As the output voltage of the power supply varies, the PMIC will detect this fluctuation and send out a reset signal when the voltage exceeds the preset range. As the voltage returns to normal range, the reset output will be released after a certain delay, which is customizable based on specific needs.

In summary, XC6121A221MG-G can detect changes in the power supply system, send out reset signals and provide power management solutions in a variety of applications. This PMIC series is designed to maximize system performance, optimize power consumption and ensure safety by reducing the likelihood of system errors from occurring.
