FAQs

What is MAX809LEUR-T?

The MAX809LEUR-T is a microprocessor supervisory circuit designed by Maxim Integrated. It is used to monitor the power supply voltage of microprocessors and microcontrollers, ensuring proper system reset and operation under all power conditions.

How Does MAX809LEUR-T Work?

The MAX809LEUR-T works by continuously monitoring the power supply voltage. If the voltage falls below a predefined threshold, it asserts a reset signal to the microprocessor or microcontroller, ensuring a proper reset and preventing erratic operation under low voltage conditions. The circuit includes a manual reset input for external system control.

How Many Pins does MAX809LEUR-T have and What are the Functions of the Pinout Configuration?

The MAX809LEUR-T is housed in a 3-pin SOT-23 package. The pinout configuration includes:

  • VCC: Power supply input pin.
  • GND: Ground pin.
  • RESET: Reset output pin for the microprocessor or microcontroller.

What are the Pros and Cons of MAX809LEUR-T?

Pros:

  • Power Monitoring: Ensures reliable system operation by monitoring the power supply voltage.
  • Reset Function: Automatically generates reset signals when voltage falls below a critical level.
  • Manual Reset Input: Allows for external control of the reset function.
  • Wide Voltage Range: Supports a wide input voltage range for versatile applications.
  • Small Package: The SOT-23 package is compact and space-efficient.

Cons:

  • Single Function: Designed specifically for power supply monitoring and reset, may not include additional features.
  • External Components: May require additional external components such as capacitors for specific applications.

Are There Any Equivalents/Alternatives to MAX809LEUR-T for Recommendation?

  • The MAX813L from Maxim Integrated is a similar microprocessor supervisory circuit with additional features.
  • Alternatives to the MAX809LEUR-T include the TPS3808 from Texas Instruments and the AS192-80 from Allegro MicroSystems.
