詳細說明

The MIC811SUY-TR is a valuable addition to any power management system, providing vital supervision and protection for microprocessors. With a wide voltage supply range of 1.6V to 5.5V, this device ensures that the system operates within safe parameters, triggering a reset signal if the voltage drops below a certain threshold. The active-low push-pull output configuration guarantees that the reset signal is only asserted when necessary, allowing for smooth and uninterrupted system operation. In addition, the inclusion of a watchdog timer adds an extra layer of security, preventing the microprocessor from hanging and resetting the system if necessary. Packed into a compact SOT-23-3 package, the MIC811SUY-TR is the perfect choice for applications with limited space, proving that size does not compromise functionality

常見問題解答

What is MIC811SUY-TR?

The MIC811SUY-TR is a low-voltage microprocessor supervisory circuit with manual reset input designed by Microchip Technology. It is commonly used to monitor the power supply voltage of microcontrollers and digital systems, ensuring proper operation and system stability.

How Does MIC811SUY-TR Work?

The MIC811SUY-TR works by continuously monitoring the supply voltage of a microcontroller or digital system. If the voltage falls below a predefined threshold, the circuit asserts a reset signal to ensure that the system restarts in a controlled manner. The manual reset input allows for a manual system reset when required.

How Many Pins does MIC811SUY-TR have and What are the Functions of the Pinout Configuration?

The MIC811SUY-TR is housed in a 3-pin SOT-23 package. The pinout configuration includes:

  • VCC: Power supply input pin.
  • MR: Manual reset input pin.
  • GND: Ground pin.

What are the Pros and Cons of MIC811SUY-TR?

Pros:

  • Low Voltage Operation: Monitors low-voltage systems, ideal for battery-powered and portable devices.
  • Automatic Reset: Safeguards systems by automatically asserting a reset signal upon detecting a low-voltage condition.
  • Manual Reset Input: Provides flexibility for manual system resets when needed.
  • Compact Package: The 3-pin SOT-23 package is space-efficient, suitable for compact designs.
  • Low Power Consumption: Operates with low power, minimizing energy consumption.

Cons:

  • External Components: May require additional external components for specific applications, such as voltage threshold setting resistors.
  • Fixed Threshold: The voltage threshold is fixed and may not be adjustable in some designs.

Are There Any Equivalents/Alternatives to MIC811SUY-TR for Recommendation?

  • The MAX6816 from Maxim Integrated is a similar microprocessor supervisory circuit with manual reset input.
  • Alternatives to the MIC811SUY-TR include the ADM803/ADM809 series from Analog Devices and the TPS3808 series from Texas Instruments.
