Detailed Pin Configuration

MIC708TMY-TR has three pins:

1. VDD: This pin is connected to the positive supply voltage.
2. GND: This pin is connected to the ground or negative supply voltage.
3. RESET: This pin outputs the reset signal when the supply voltage falls below the threshold.

Functional Features

• Under-voltage detection: MIC708TMY-TR continuously monitors the supply voltage and detects when it drops below the set threshold.
• Reset signal generation: When the voltage falls below the threshold, the IC generates a reset signal to ensure proper functioning of the connected circuitry.
• Adjustable threshold: The reset threshold voltage can be adjusted by connecting external resistors to the IC.
• Fixed timeout period: The reset signal remains active for a fixed period (typically 140ms) after the voltage rises above the threshold.

Advantages and Disadvantages

Advantages

• Reliable voltage monitoring and reset functionality.
• Low power consumption.
• Wide operating voltage range.
• Compact package size.
• Adjustable reset threshold.

Disadvantages

• Fixed timeout period may not suit all applications.
• Limited pin configuration options.

Working Principles

MIC708TMY-TR operates based on a voltage comparator circuit. It compares the supply voltage with the set threshold voltage. When the supply voltage drops below the threshold, the comparator triggers the reset signal. The reset signal remains active for a fixed period, allowing the connected circuitry to stabilize before normal operation resumes.

Detailed Application Field Plans

MIC708TMY-TR finds applications in various electronic devices where voltage monitoring and reset functions are crucial. Some common application fields include:

1. Microcontrollers: Ensuring proper initialization and reliable operation of microcontrollers.
2. Embedded Systems: Providing voltage monitoring and reset functionality in embedded systems.
3. Power Management: Protecting sensitive components from voltage fluctuations in power management circuits.
4. Battery-Powered Devices: Extending battery life by efficiently managing voltage levels in portable devices.
