• Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

MIC803-31D2VC3-TR has three pins:

1. VDD: Power supply input pin.
2. GND: Ground reference pin.
3. RESET: Output pin that provides a reset signal when the monitored voltage falls below the threshold.

Functional Features

• Monitors the voltage level continuously.
• Generates a reset signal when the voltage drops below the specified threshold.
• Maintains the reset signal for a specific timeout period after the voltage returns above the threshold.
• Provides accurate and reliable voltage monitoring.

Advantages

• Low power consumption helps in energy-efficient designs.
• Wide operating voltage range makes it suitable for various applications.
• Small package size allows for space-saving designs.
• High accuracy ensures precise voltage monitoring.
• Active low reset output signal is compatible with most microcontrollers.

Disadvantages

• The reset timeout period may not be adjustable, limiting flexibility in certain applications.
• Limited availability of alternative models from other manufacturers.

Working Principles

MIC803-31D2VC3-TR operates by comparing the input voltage with the preset threshold voltage. When the input voltage drops below the threshold, the reset output is activated, indicating a power failure or unstable voltage condition. The reset signal remains active for the specified timeout period after the voltage rises above the threshold, allowing the system to stabilize before resuming normal operation.
