  • Generates a reset signal when the voltage falls below the programmable threshold.
  • Programmable reset timeout period allows customization for specific applications.
  • Low quiescent current ensures minimal power consumption.
  • Small package size enables space-efficient designs.

Advantages and Disadvantages

Advantages: - Precise voltage monitoring and resetting functionality. - Programmable delay and threshold options provide flexibility. - Low-power operation extends battery life. - Small package size saves board space.

Disadvantages: - Limited threshold voltage options may not suit all applications. - Programmable timeout period has a maximum limit of 640ms.

Working Principles

The MAX6728KAVDD3+T operates by continuously monitoring the voltage level at the VCC pin. It compares this voltage with the programmable threshold voltage set by the user. If the VCC voltage falls below the threshold, the RESET pin is activated, generating a reset signal. The reset signal remains active until the VCC voltage rises above the threshold or the programmable timeout period elapses.
