PMIC - Supervisors, one of the most important branch of power management integrated circuit (PMIC) field, works as the regulators and controllers of voltage, current and power between the main power supplies and the other electronic components or electronic circuits of an electronic device. For instance, XC6108N27AGR-G, as one of the common used PMIC - Supervisor, is a 20V voltage supervisor which is applicable for battery-oriented portable systems and controllers. Generally speaking, XC6108N27AGR-G can successfully monitor the system status and control the power supply for the target devices in order to assure the continual operation of the electronic systems.

In terms of its application scenarios, XC6108N27AGR-G is one of the good choice for automotive electronics, notebook PCs, industrial PCs, family PCs, camcorders, wireless communication products and gaming machines. Take automotive electronics as an example, it is necessary to accurately monitor the power supply state and battery charge status, and the XC6108N27AGR-G has the functions to identify abnormal states of the car engine, and to secure the nominal operation voltage required by the car systems, thus maintain the normal operation of the car.

Talking of the design and working principle of XC6108N27AGR-G, it is based on two special voltage supervisors, named as C COP and F COP, which have the ability to monitor and control the system power condition. Specifically, C COP here stands for current COP, it is used to monitor the current status of the car. Usually the electrical current keeps changing in a certain range, if the current is too high, then a current COP will be activated to judge the situation and to control the current back in the proper range. Similar to C COP, F COP means that the voltage COP is functioning here to control the voltage status of the car.

Also, in order to achieve its high performance of working, XC6108N27AGR-G is designed with a number of resistors and capacitors around its two supervisors, to enable them to quickly detect the changes of the system power status. For example, the resistor R COP applied with C COP can enlarge the sensing range of current, ensuring the higher detection accuracy. And, parallel to the R COP is the capacitor C RST , which can provide the necessary filter function to reduce the noise and to keep the junction voltage stable of C COP. All these circuit design constitute the key factors of the working principle of XC6108N27AGR-G: to monitor, detect and control the system current, voltage status.

Apart from the voltage monitoring and controlling, XC6108N27AGR-G is also equipped with many other built-in functions like the wake-up timer and key input detection. With the wake-up timer, XC6108N27AGR-G can postpone or enhance the signal from other PMIC or other electronic components to active the target device. That is to say, it can adjust the power supply status for the target device to certain extent and improve the system performance. Also, regarding key input control, XC6108N27AGR-G can actively monitor the input status and the signal which corresponds to a certain key, setting the exposure and detect accuracy more precisely.

To sum up, XC6108N27AGR-G, as one of the common and demanding PMIC - Supervisors, is typically used in automotive electronics, some electronic products and gaming machines, etc. And the key functions of XC6108N27AGR-G include current, voltage monitoring and controlling, power supply status controlling, wake-up timer setting and key input controlling. All of these functions are the basic and effective methods for assuring the continual operation and reliable performance of the target system.
