Package

MIC803-46D3VM3-TR is available in a small SOT-23-3 package.

Essence

The essence of this product lies in its ability to monitor the voltage level and provide a reset signal when the voltage falls below a certain threshold.

Packaging/Quantity

MIC803-46D3VM3-TR is typically packaged in reels, with each reel containing a specific quantity of ICs. The exact quantity may vary depending on the manufacturer's specifications.

Specifications

• Supply Voltage Range: 1.6V to 5.5V
• Reset Threshold Voltage: 4.6V
• Reset Timeout Period: 140ms
• Quiescent Current: 1µA (typical)
• Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

MIC803-46D3VM3-TR has three pins:

1. VDD: Power supply input pin (+)
2. GND: Ground pin (-)
3. RESET: Reset output pin

Functional Features

• Monitors the supply voltage continuously
• Generates a reset signal when the voltage drops below the specified threshold
• Reset signal remains active for the defined timeout period after the voltage rises above the threshold again
• Provides a reliable indication of power supply status

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 precise voltage monitoring
• Reset output signal facilitates system recovery after power loss

Disadvantages

• Fixed reset threshold voltage may not be suitable for all applications
• Limited timeout period may not be sufficient for certain system recovery processes

Working Principles

MIC803-46D3VM3-TR operates by comparing the supply voltage with the preset threshold voltage. When the supply voltage drops below the threshold, the internal circuit triggers the reset output, indicating a power failure. The reset signal remains active for the defined timeout period, allowing the system to recover before normal operation resumes.
