• Quiescent Current: 1µA (typical)
• Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

MIC803-46D2VM3-TR has three pins:

1. VDD: Power supply input pin (+1.6V to +5.5V).
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 specified threshold.
• The reset signal remains active-low until the supply 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

• The reset timeout period is fixed and cannot be adjusted.
• Limited availability of alternative models with different reset threshold voltages.

Working Principles

MIC803-46D2VM3-TR operates by comparing the supply voltage with the preset threshold voltage. When the supply voltage drops below the threshold, the internal circuitry triggers the reset output to go low. The reset signal remains low until the supply voltage rises above the threshold and the timeout period elapses. This ensures that the microcontroller or digital system is properly reset before resuming normal operation.

Detailed Application Field Plans

MIC803-46D2VM3-TR finds applications in various electronic devices where voltage monitoring and reliable reset functions are required. Some potential application fields include:

1. Microcontrollers and embedded systems
2. Power management circuits
3. Battery-powered devices
4. Industrial automation systems
5. Automotive electronics
6. Medical equipment

Detailed and Complete Alternative Models

While MIC803-46D2VM3-TR is a popular choice for voltage monitoring and reset functions, there are alternative models available from different manufacturers. Some notable alternatives include:
