• Reset Threshold Voltage Options: 2.93V, 4.63V
• Reset Timeout Period: 140ms (typical)
• Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

MIC809SU-TR has three pins:

1. VDD: Power supply input pin
2. GND: Ground reference pin
3. RESET: Active-low reset output pin

Functional Features

• Voltage Monitoring: MIC809SU-TR continuously monitors the supply voltage.
• Reset Generation: When the supply voltage drops below the specified threshold, the reset output becomes active-low.
• Reset Timeout: The reset output remains low for a fixed timeout period after the supply voltage rises above the threshold.

Advantages and Disadvantages

Advantages

• Low power consumption makes it suitable for battery-powered devices.
• Wide operating voltage range allows compatibility with various systems.
• Small package size enables space-saving designs.
• High accuracy ensures reliable voltage monitoring.

Disadvantages

• Limited reset threshold voltage options may not cater to all applications.
• Fixed reset timeout period may not be adjustable for specific requirements.

Working Principles

MIC809SU-TR operates by comparing the supply voltage with the preset threshold voltage. When the supply voltage falls below the threshold, the internal circuitry triggers the reset output to become active-low. The reset output remains low for a fixed timeout period after the supply voltage rises above the threshold.

Detailed Application Field Plans

MIC809SU-TR finds applications in various electronic devices that require voltage monitoring and reset functions. Some potential application fields include:

1. Microcontrollers: MIC809SU-TR can be used to ensure proper system initialization and prevent erratic behavior during power-up or voltage fluctuations.
2. Embedded Systems: It provides reliable reset functionality to ensure stable operation of embedded systems.
3. Industrial Control Systems: MIC809SU-TR helps maintain system integrity by resetting the microcontroller when the supply voltage drops below the specified threshold.

Detailed and Complete Alternative Models

Some alternative models that offer similar functionality to MIC809SU-TR are:

1. MAX809: Manufactured by Maxim Integrated, it offers a wide range of reset threshold voltage options.
2. MCP809: Produced by Microchip Technology, it features adjustable reset timeout periods.
