- VDD: Power supply input pin.
- GND: Ground reference pin.
- MR: Manual reset input pin.
- RESET: Active-low reset output pin.
- VOUT: Voltage monitor output pin.
Functional Features
- Voltage Monitoring: MIC1810-10U-TR continuously monitors the input voltage and compares it with the threshold voltage.
- Reset Generation: When the input voltage falls below the threshold voltage, the reset output is asserted, indicating a low-voltage condition.
- Manual Reset: The manual reset input allows for an external reset signal to override the voltage monitoring function.
- Reset Timeout: After the input voltage rises above the threshold voltage, the reset output remains asserted for a fixed timeout period before deasserting.
Advantages and Disadvantages
Advantages
- Wide operating voltage range allows for compatibility with various systems.
- Low power consumption minimizes energy usage.
- Small package size enables space-saving designs.
- High accuracy ensures reliable voltage monitoring.
Disadvantages
