Detailed Pin Configuration

MIC803-26D4VC3-TR has three pins:

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

Functional Features

• Monitors the supply voltage continuously
• Generates a reset signal when the voltage drops below the threshold
• Reset signal remains active-low until the voltage rises above the threshold and the timeout period elapses
• Provides a reliable reset function for microcontrollers and other digital systems

Advantages and Disadvantages

Advantages

• Low power consumption makes it suitable for battery-powered devices
• Wide operating voltage range allows for versatile applications
• Small package size saves board space
• High accuracy ensures reliable voltage monitoring

Disadvantages

• Reset timeout period may not be adjustable, limiting flexibility in certain applications
• Lack of additional features such as hysteresis or adjustable threshold voltage

Working Principles

MIC803-26D4VC3-TR operates by comparing the supply voltage with a fixed threshold voltage. When the supply voltage drops below the threshold, the reset output is activated and held low. The reset signal remains active until the supply voltage rises above the threshold and the timeout period elapses.
