Detailed Pin Configuration

MIC809MU-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: MIC809MU-TR continuously monitors the supply voltage.
• Reset generation: When the voltage drops below the set threshold, the reset output becomes active low.
• Reset timeout: The reset signal remains active low for a specific period after the 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 and timeout period options may not meet the requirements of all applications.
• Lack of adjustable threshold voltage limits customization possibilities.

Working Principles

MIC809MU-TR utilizes a voltage comparator to continuously compare the supply voltage with the set threshold voltage. When the supply voltage falls below the threshold, the comparator triggers the reset output to become active low. The reset signal remains active low for a specific timeout period after the voltage rises above the threshold.

Detailed Application Field Plans

MIC809MU-TR finds applications in various electronic devices where voltage monitoring and reset functions are crucial. Some potential application fields include:

1. Microcontrollers: Ensuring proper system initialization and preventing data corruption during power fluctuations.
2. Industrial Control Systems: Providing reliable reset functionality for critical control units.
3. Automotive Electronics: Monitoring battery voltage and generating reset signals for safety-critical systems.
4. Consumer Electronics: Preventing malfunction or damage due to voltage drops in portable devices.
