Working Principle of XC6123C733MR-G

The XC6123C733MR-G voltage supervisor provides a regulated voltage supply and supervise power-on/off conditions. It generates active high/low reset/power-good signals based on the status of the power supply voltage. When the power supply voltage comes above a preset threshold voltage, for example, when the system is powered on, it asserts the power-good output signal and de-asserts the reset output signal. Similarly, when the power supply voltage drops below a preset threshold voltage, for example, when the system is powered off, it de-asserts the power-good output signal and asserts the reset output signal.

The XC6123C733MR-G also has a built-in low-battery detector circuit. This feature allows it to detect a low voltage condition in a power source by monitoring the battery voltage. If the battery voltage is below the preset threshold, the output signal will be used to trigger the power down sequence.

The XC6123C733MR-G also has a low supply current feature to enable a low power operation. This feature allows it to maintain system power consumption at a minimum level. And it also has a programmable reference voltage comparison circuit to provide adjustable reset/power-good thresholds.

Conclusion

The XC6123C733MR-G is a low power voltage supervisor for nano-to-microapm power scaling applications. It provides a regulated voltage supply and can be used for power-on/off and voltage supervisory applications in consumer electronics, telecom and datacom, industrial control and automotive applications. It offers a variety of features such as undervoltage, overvoltage and power-good monitoring, current-limited output, thermal shutdown, adjustable overvoltage protection, low-battery detector circuit, low supply current and adjustable reset/power-good thresholds.
