Detailed Pin Configuration

MIC803-30D3VC3-TR has three pins:

1. VCC: Connect this pin to the positive supply voltage.
2. GND: Connect this pin to the ground.
3. RESET: This open-drain output pin provides an active-low reset signal.

Functional Features

• Accurate voltage monitoring and reset generation.
• Wide operating voltage range.
• Low quiescent current consumption.
• Open-drain output for flexibility in interfacing with other devices.
• Active-low RESET output for easy integration into digital systems.

Advantages and Disadvantages

Advantages

• Wide operating voltage range allows compatibility with various systems.
• Accurate voltage monitoring ensures reliable operation of microcontrollers and digital systems.
• Low quiescent current consumption minimizes power consumption.
• Open-drain output provides flexibility in connecting to other devices.
• Active-low RESET output simplifies integration into digital systems.

Disadvantages

• Reset timeout period accuracy may not be suitable for applications requiring precise timing.
• Power-on reset delay of 20ms may cause a slight delay in system startup.

Working Principles

MIC803-30D3VC3-TR operates by continuously monitoring the supply voltage. When the voltage drops below the preset threshold (3.0V), the device generates an active-low reset signal on the RESET pin. The reset signal remains active until the voltage rises above the threshold or the reset timeout period (140ms) elapses.
