Functional Features

• Monitors the voltage level of the power supply continuously.
• Generates a reset signal when the voltage falls below the set threshold.
• Provides an adjustable or fixed reset timeout period.
• Includes a manual reset input for external reset control.

Advantages

• Compact size allows for easy integration into space-constrained designs.
• Wide supply voltage range enables compatibility with various power sources.
• Low power consumption helps to conserve energy in battery-powered applications.
• Adjustable reset timeout period offers flexibility in system design.

Working Principles

The MAX6721AUTTGD6+T operates by continuously monitoring the voltage level of the power supply connected to its VCC pin. When the voltage falls below the set threshold, the IC generates a reset signal on the RESET OUT pin. The reset timeout period can be adjusted or fixed depending on the specific model chosen. Additionally, the MR pin allows for manual reset control if required.
