Working Principle
The working principle of the MCP101-450DI/TO is as follows:
The integrated voltage supervisor, programmable control logic, comprehensive over temperature / over voltage /under voltage protection, power-on reset, and watchdog circuit with time out work together to reset any active devices, and provide protection from voltage variations. The internal oscillator clock has programmable option, and it can be used to set timeout of the watchdog circuit. The low power standby mode helps to reduce the power consumption of the system and the low power active mode allows more energy to be used when needed. The wide input voltage range from 0.9V to 3.6V assures that the device can be used in a variety of applications. The monitor and control of the voltage supply is done using SPI/I2C compatible interface. The MCP101-450DI/TO also includes a Power Good signal function that provides feedback to the system to allow the timing of the critical functions of the system to be rewritten. This feedback can be used to detect when the power is stable and the system is ready to work. The Reset Output Output pin provides an active low signal when the system is in time-out, and it initiates reset signal to active system devices until the power supply is stable.

Conclusion
In conclusion, the MCP101-450DI/TO is a PMIC-Supervisors that offers a variety of features such as integrated voltage supervisor, programmable control logic, comprehensive over temperature/ over voltage/under voltage protection, power ON reset and a watchdog circuit with timeout. The low power standby mode and low power active mode, as well as the wide input voltage range from 0.9V to 3.6V, allow for use in different applications. With its Power Good signal function and Reset Output Output pin, the MCP101-450DI/TO is suitable for applications in automatic control systems, consumer electronics, telecommunications, home appliances or any system that requires power-on reset protection.
