3. RESET: Reset output pin

Functional Features

• Voltage monitoring: MIC803-29D4VM3-TR continuously monitors the supply voltage and generates a reset signal when it falls below the threshold voltage.
• Reset signal generation: When the supply voltage drops below the threshold, the reset output pin goes low, indicating a reset condition.
• Reset timeout: The reset signal remains active for a specific timeout period, allowing the device to fully reset before returning to normal operation.

Advantages and Disadvantages

Advantages

• Low power consumption ensures minimal impact on overall device power consumption.
• Wide operating voltage range makes it compatible with various electronic devices.
• Small package size allows for space-saving integration into compact designs.
• High accuracy ensures reliable voltage monitoring and reset functionality.
