Introduction

MIC707N is a Microchips® Supervisory IC. This device is intended for monitoring battery, power supply and other device voltage levels in a variety of applications. It is specifically designed to provide precise input and output control of microprocessor and digital logic functions. This IC includes voltage monitor, voltage supervisor, and over temperature protection. In addition, it also provides protection against reverse polarity. The MIC707N provides protection against undervoltage, overvoltage, and overheat events.It is designed to be used in a variety of applications such as automotive, industrial, medical, and consumer electronics. In terms of power supply, this IC is designed to support both battery-operated and non-battery-operated applications.

Application Field

The MIC707N is used in many automotive applications, including engine control and engine start systems. Additionally, the IC is suitable for providing protection from unintended power supply or overvoltage or undervoltage events. It is ideal for applications where precise control of voltage monitoring is required.In addition to automotive applications, the MIC707N can also be used to protect and control electronic systems in various industrial, medical and consumer electronics applications. It is suitable for providing protection from reverse polarity, overvoltage, undervoltage and overcurrent events. The device can also provide input or output logic error checking, making it suitable for a variety of systems.

Working Principle

The MIC707N monitors the input voltage and converts it into a digital logic level output. The output reflects the condition of the monitored voltage. The output will be logic low when the monitored voltage is below the lower threshold or above the upper threshold. The output will switch to a logic high when the voltage is within the specified voltage range.The device is designed with an adjustable voltage monitor voltage range and over temperature protection of up to 150°C. The monitored voltage range is programmable via an external resistor. The MIC707N also provides reverse polarity protection and is designed to protect against power supply interruptions.The IC also has a “fail safe” feature. When the monitored voltage exceeds the specification or temperature threshold, then the output will remain logic low, effectively shutting down the system.

Conclusion

The MIC707N is an ideal IC for providing protection against power supply interruptions, reverse polarity, overvoltage and undervoltage events. The IC can also be used for a variety of other applications, including engine control and engine start systems. The MIC707N is designed with adjustable voltage monitor voltage range and over temperature protection of up to 150°C. In addition, the device features a “fail safe” feature, which ensures that the system will remain shut down in case of an overvoltage or over temperature event.
