FAQs

What is MAX811TEUS+?

The MAX811TEUS+ is a microprocessor supervisory circuit designed by Maxim Integrated. It is used to monitor the power supply and the activity of a microprocessor, providing a reset signal in the event of power-on reset or brownout conditions. This helps ensure reliable operation of the microprocessor-based system.

How Does MAX811TEUS+ Work?

The MAX811TEUS+ works by continuously monitoring the supply voltage and the microprocessor activity. If the supply voltage falls below a predefined threshold or if the microprocessor enters an inactive state, the MAX811TEUS+ asserts a reset signal to indicate a reset condition. Additionally, it includes a manual reset input for external reset control.

How Many Pins does MAX811TEUS+ have and What are the Functions of the Pinout Configuration?

The MAX811TEUS+ is housed in a 6-pin SOT23 package. The pinout configuration includes:

RESET: Reset output signal.
GND: Ground connection.
MR: Manual reset input for external reset control.
IN: Supply voltage monitoring input.
VCC: Power supply voltage input.

What are the Pros and Cons of MAX811TEUS+?

Pros:

Power Monitoring: Provides reliable monitoring of power supply conditions for robust system operation.
Reset Signal: Generates a reset signal when power-on reset or brownout conditions occur, ensuring proper system initialization.
Manual Reset Input: Includes a manual reset input for external reset control, allowing flexibility in system design.
Small Package: Housed in a compact SOT23 package, suitable for space-constrained designs.

Cons:

External Component: May require an external pull-up resistor for the manual reset input.
Sensitivity to Noise: Careful consideration of noise immunity and proper decoupling is important for reliable operation.

Are There Any Equivalents/Alternatives to MAX811TEUS+ for Recommendation?

The MAX809 from Maxim Integrated is a similar microprocessor supervisory circuit with different threshold options.
