Detailed Pin Configuration

The MIC810RYC3 is a three-pin device with the following pin configuration:

1. VCC: Connects to the positive supply voltage.
2. GND: Connects to the ground reference.
3. RESET: Output pin that provides a reset signal when the monitored voltage falls below the threshold.

Functional Features

• Monitors the supply voltage and generates a reset signal when it drops below the specified threshold.
• Provides a stable reset output during power-up and power-down sequences.
• Low quiescent current consumption, making it suitable for battery-powered applications.
• Built-in hysteresis prevents false triggering due to voltage fluctuations or noise.

Advantages and Disadvantages

Advantages

• Wide supply voltage range allows compatibility with various systems.
• Multiple reset threshold and timeout options provide flexibility in different applications.
• Small package size enables space-saving designs.
• Low-power consumption extends battery life in portable devices.

Disadvantages

• Limited number of reset threshold and timeout options may not meet the requirements of all applications.
• Lack of additional features, such as adjustable delay or manual reset input.

Working Principles

The MIC810RYC3 operates by continuously monitoring the supply voltage. When the voltage drops below the programmed threshold, the internal comparator triggers a reset signal on the RESET pin. This signal remains active until the voltage rises above the threshold and the reset timeout period elapses.

Detailed Application Field Plans

The MIC810RYC3 is commonly used in various electronic systems where reliable power supply monitoring is critical. Some typical application fields include:

1. Microcontrollers and microprocessors
2. Embedded systems
3. Industrial control systems
4. Automotive electronics
5. Portable devices

Detailed and Complete Alternative Models

• MIC809: Similar to MIC810RYC3 but with an open-drain output instead of push-pull.
• MAX809: Comparable device with additional features like adjustable reset timeout and manual reset input.
• TC54: Alternative option with a wider range of reset threshold voltage options.

Note: This list is not exhaustive, and there are other alternative models available from different manufacturers.
