Functional Features

• Voltage Monitoring: MIC812MUY-TR continuously monitors the supply voltage and compares it with the preset threshold.
• Reset Generation: When the supply voltage falls below the threshold, the reset output is asserted, indicating the need for a system reset.
• Manual Reset: The manual reset pin allows for an external reset signal to override the internal monitoring circuitry.
• Adjustable Threshold: MIC812MUY-TR offers an adjustable threshold option, allowing customization based on specific application requirements.
• Reset Timeout: The reset output remains asserted for a fixed timeout period after the supply voltage rises above the threshold.

Advantages and Disadvantages

Advantages

• Reliable voltage monitoring and reset functionality
• Low power consumption ensures minimal impact on overall system performance
• Compact size enables integration into space-constrained designs
• Wide operating temperature range allows for use in various environments

Disadvantages

• Lack of advanced features compared to more specialized voltage monitoring ICs
• Limited threshold options may not cater to all voltage monitoring requirements

Working Principles

MIC812MUY-TR operates by continuously monitoring the supply voltage using an internal voltage comparator. When the voltage falls below the preset threshold, the reset output is activated, indicating the need for a system reset. The manual reset pin allows for an external reset signal to override the internal monitoring circuitry. The reset output remains asserted for a fixed timeout period after the supply voltage rises above the threshold.
