  • Precision reset generation: The reset output remains asserted for a fixed duration after the power supply voltage rises above the threshold voltage.
  • Manual reset input: The MR pin allows for manual assertion of the reset signal, overriding the voltage monitoring function.
  • Low-power consumption: With a quiescent current of only 3µA, the MAX810RTRG minimizes power consumption in battery-powered applications.

Advantages and Disadvantages

Advantages: - Precise voltage monitoring ensures system reliability - Low-power consumption extends battery life - Small form factor package allows for space-efficient designs

Disadvantages: - Limited threshold voltage options may not suit all applications - Lack of adjustable reset duration limits flexibility in certain scenarios

Working Principles

The MAX810RTRG operates by comparing the power supply voltage with a fixed threshold voltage. When the power supply voltage drops below the threshold, the reset output is asserted, indicating a low-voltage condition. Once the power supply voltage rises above the threshold, the reset output remains asserted for a fixed duration before deasserting.

Detailed Application Field Plans

The MAX810RTRG finds applications in various fields, including:

  1. Microcontrollers: Ensuring reliable operation by monitoring the power supply voltage and initiating a reset if necessary.
  2. Embedded Systems: Protecting critical components from improper operation due to voltage fluctuations.
  3. Battery-Powered Devices: Extending battery life by minimizing power consumption through accurate voltage monitoring.
