Power management integrated circuits (PMIC) are growing in popularity. As new technologies and applications have become available, PMIC have become more efficient and provide more features. The MIC705MY is an example of a PMIC- Supervisors manufactured by Microchip Technology. This device provides protection and supervision for a number of applications, including system monitoring and reset. In this article, we will discuss the MIC705MY\'s application fields and working principles.

1. Application Fields

The MIC705MY is a voltage supervisor device, mainly used for protecting systems from overvoltage and undervoltage conditions. It can detect three different thresholds within its input window. The first is its supply voltage, which is the voltage monitored by the internal comparator. The second is its alarm threshold, which is triggered when the supply voltage drops below the alarm threshold. Lastly, it has a reset threshold, which is triggered when the supply voltage drops below the reset threshold. When this happens, the MIC705MY will output a reset signal.

In addition to its over- and under-voltage protection, the MIC705MY can also be used to monitor system power supply conditions. It can detect if the system is running too high or too low in voltage, allowing the user to quickly detect system faults. It can also be used to monitor the system\'s temperature and current, as well as providing a reset signal in case of a system fault.

2. Working Principle

The MIC705MY is a voltage supervisor device, which means it monitors the supply voltage of a system and triggers a reset signal when the voltage drops below a certain threshold. The device works by running a comparison between the system\'s supply voltage and the given reset and alarm thresholds. When the supply voltage is higher than the given thresholds, the internal comparator remains in its initialized state and the output remains low.

When the supply voltage drops below the given reset or alarm thresholds, the internal comparator triggers and the output goes high. This triggers a reset signal, which can be used to reset the system. The output can also be connected to an interrupt line to alert the system if a fault has occurred.

The MIC705MY also has two separate static outputs, Fault and Power Good, which are active low and are used to detect power supply anomalies. The Fault output is triggered when the supply voltage drops below the given alarm threshold and the Power Good output is triggered when the supply voltage rises above the given reset threshold.

Conclusion

The MIC705MY is an example of a PMIC- Supervisors manufactured by Microchip Technology. It is mainly used to protect systems from overvoltage and undervoltage conditions and also to alert the system of power supply anomalies. The device works by running a comparison between the system\'s supply voltage and the given reset and alarm thresholds, and then triggering a reset signal if the supply voltage drops below a certain threshold. The MIC705MY also has two separate static outputs, Fault and Power Good, which are used to detect power supply anomalies.
