Detailed Pin Configuration

The MIC811JU TR has a SOT-23-3 package with the following pin configuration:

  • Pin 1: GND (Ground)
  • Pin 2: RESET (Reset Output)
  • Pin 3: VCC (Supply Voltage)

Functional Features

  • Monitors the supply voltage and asserts the reset output when it falls below the specified threshold.
  • Provides a precision monitoring solution for microcontrollers, DSPs, and other digital systems.
  • Low power consumption, making it suitable for battery-powered applications.
  • Offers various reset threshold voltage and timeout period options for flexibility.

Advantages

  • Small form factor and low profile package enable space-saving designs.
  • Wide supply voltage range allows compatibility with different systems.
  • Precision monitoring ensures reliable operation of digital systems.
  • Low power consumption extends battery life in portable devices.

Disadvantages

  • Limited number of reset threshold voltage and timeout period options.
  • Not suitable for high-voltage applications due to the maximum supply voltage limitation.

Working Principles

The MIC811JU TR operates by continuously monitoring the supply voltage. When the voltage falls below the programmed threshold, the reset output is asserted, indicating a power failure or an unstable condition. The reset output remains active until the supply voltage rises above the threshold and the reset timeout period elapses.

Detailed Application Field Plans

The MIC811JU TR is commonly used in various applications, including:

  1. Microcontroller-based systems
  2. Digital signal processors (DSPs)
  3. Embedded systems
  4. Battery-powered devices
  5. Industrial control systems
  6. Automotive electronics
