Detailed Pin Configuration

The MAX810LTRG has four pins:

  1. GND: Ground connection.
  2. RESET: Active-low reset output.
  3. MR: Manual reset input. Pulling this pin low forces a reset.
  4. VCC: Power supply input.

Functional Features

  • Monitors the power supply voltage continuously.
  • Generates a reset signal when the voltage drops below the set threshold.
  • Provides a manual reset option through the MR pin.
  • Offers adjustable or fixed reset timeout periods.
  • Low-power consumption for energy-efficient applications.
  • Precision voltage monitoring for reliable system operation.

Advantages and Disadvantages

Advantages: - Wide supply voltage range allows compatibility with various systems. - Multiple reset threshold options cater to different voltage requirements. - Adjustable reset timeout period offers flexibility in system design. - Small package size enables space-saving PCB layouts. - Low-power consumption prolongs battery life in portable devices.

Disadvantages: - Limited to voltage monitoring and reset generation functionality. - Requires an external pull-up resistor for the MR pin.

Working Principles

The MAX810LTRG operates by comparing the supply voltage with a preset threshold. When the voltage falls below the threshold, the internal circuitry generates a reset signal, which remains active until the voltage rises above the threshold or a timeout period elapses. The manual reset input allows for immediate system reset when required.
