```

---

| | --| VCC |-- --| /RESET|-- --| GND |-- |_______| ```

Pin Description: - VCC: Power supply pin (+) - /RESET: Active-low reset output - GND: Ground pin (-)

Functional Features

1. Voltage Monitoring: MIC810SU-TR continuously monitors the supply voltage.
2. Reset Generation: When the supply voltage drops below the specified threshold, the /RESET pin is asserted low, generating a reset signal.
3. Hysteresis: The IC incorporates hysteresis to prevent oscillation of the reset output during power-up or noisy conditions.
4. Power-On Reset Delay: It provides a fixed delay time to ensure stable power-on reset operation.

Advantages and Disadvantages

Advantages

• Low power consumption enables energy-efficient designs.
• Small package size allows for compact circuit layouts.
• Wide operating voltage range makes it compatible with various applications.
• Hysteresis prevents false triggering of the reset signal.

Disadvantages

• Limited reset threshold voltage options may not suit all voltage monitoring requirements.
• Lack of adjustable reset delay limits customization options.

Working Principles

MIC810SU-TR operates by comparing the supply voltage with the preset threshold voltage. When the supply voltage falls below the threshold, the internal circuitry asserts the /RESET pin low, indicating a reset condition. The reset signal remains active until the supply voltage rises above the threshold and stabilizes.

Application Field Plans

MIC810SU-TR finds applications in various electronic devices that require reliable voltage monitoring and reset functionality. Some potential application fields include: - Microcontrollers and microprocessors - Embedded systems - Battery-powered devices - Industrial control systems - Automotive electronics
