Detailed Pin Configuration

MIC803-26D2VM3-TR has three pins:

1. VDD: Power supply input pin.
2. GND: Ground reference pin.
3. RESET: Output pin that indicates the status of the device being monitored.

Functional Features

• Voltage monitoring: The MIC803-26D2VM3-TR continuously monitors the voltage level and generates a reset signal when it falls below the specified threshold.
• Reset function: The device asserts the RESET pin low during a voltage drop, triggering a system reset.
• Reset timeout: After the voltage returns to normal, the reset signal remains active for a specific timeout period before deasserting.

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

• The reset timeout delay may not be adjustable, limiting flexibility in certain applications.
• Lack of additional features such as hysteresis or adjustable threshold voltage.

Working Principles

MIC803-26D2VM3-TR operates by comparing the input voltage with the preset threshold voltage. When the voltage drops below the threshold, the device generates a reset signal. This signal remains active for a specific timeout period after the voltage returns to normal, ensuring stability during power fluctuations.

Detailed Application Field Plans

MIC803-26D2VM3-TR finds applications in various electronic devices, including but not limited to: - Microcontrollers - Embedded systems - Power management circuits - Battery-powered devices - Industrial control systems
