  • Package type: SOT-23-3
  • Essence: Voltage supervisor with a fixed threshold
  • Packaging/Quantity: Tape and reel, 3000 units per reel

Specifications

The MIC1815-20UY-TR has the following specifications:

  • Supply voltage range: 1.0V to 6.0V
  • Operating temperature range: -40°C to +85°C
  • Quiescent current: 10µA (typical)
  • Output type: Active low push-pull
  • Reset timeout period: 140ms (typical)

Pin Configuration

The MIC1815-20UY-TR has a simple pin configuration with three pins:

  1. VCC: Power supply input
  2. GND: Ground reference
  3. RESET: Active low reset output

Functional Features

The key functional features of MIC1815-20UY-TR are as follows:

  • Monitors the voltage level and generates a reset signal when it falls below the threshold.
  • Provides a stable reset output during power-up and power-down sequences.
  • Offers a fixed voltage threshold of 2.0V for accurate monitoring.

Advantages and Disadvantages

Advantages: - Low quiescent current consumption - Small package size for space-constrained applications - Fixed voltage threshold ensures precise monitoring

Disadvantages: - Fixed threshold may not be suitable for all voltage monitoring requirements - Limited reset timeout period may not be ideal for certain applications

Working Principles

The MIC1815-20UY-TR operates based on a voltage comparator circuit. It compares the input voltage with the fixed threshold of 2.0V. When the input voltage drops below this threshold, the reset output is activated, indicating a low voltage condition. The reset output remains active until the input voltage rises above the threshold.

Detailed Application Field Plans

The MIC1815-20UY-TR finds applications in various electronic systems where voltage monitoring and control are critical. Some potential application fields include:

  1. Battery-powered devices: Ensures proper shutdown or system reset when battery voltage drops below a safe level.
  2. Microcontroller systems: Provides a reliable reset signal during power-up to ensure proper initialization.
  3. Industrial control systems: Monitors power supply voltages to prevent damage to sensitive components.
