Detailed Pin Configuration

MIC810LU-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 a reset signal when the monitored voltage falls below the threshold.

Functional Features

• Voltage Monitoring: MIC810LU-TR continuously monitors the input voltage and compares it with the preset threshold voltage.
• Reset Signal Generation: When the monitored voltage drops below the threshold, the RESET pin goes low, generating a reset signal.
• Reset Timeout: The reset signal remains active for a specific timeout period, ensuring that the device resets properly even if the voltage fluctuates momentarily.

Advantages and Disadvantages

Advantages

• Compact size allows for easy integration into various electronic devices.
• Wide operating voltage range makes it compatible with different power supply configurations.
• High accuracy ensures reliable voltage monitoring and reset functionality.

Disadvantages

• Limited options for threshold voltage and timeout period may not suit all applications.
• Lack of additional features, such as adjustable threshold voltage or hysteresis, may limit its use in certain scenarios.

Working Principles

MIC810LU-TR operates by comparing the input voltage with the preset threshold voltage. When the input voltage falls below the threshold, the reset signal is activated. The reset signal remains active for the specified timeout period, allowing the device to reset properly. Once the input voltage rises above the threshold, the reset signal is deactivated.

Detailed Application Field Plans

MIC810LU-TR finds applications in various electronic devices where voltage monitoring and reset functions are crucial. Some potential application fields include:

1. Microcontrollers: MIC810LU-TR can be used to ensure proper reset and initialization of microcontrollers when the power supply voltage drops below a certain level.
2. Embedded Systems: It can be employed in embedded systems to monitor the power supply voltage and initiate a system reset if necessary.
3. Battery-Powered Devices: MIC810LU-TR can be utilized in battery-powered devices to prevent improper operation due to low battery voltage.
