Functional Features

Voltage Monitoring

ADM811ZART-REEL continuously monitors the supply voltage. When the voltage drops below the specified threshold, it triggers a reset signal.

Reset Function

The device provides a reset signal to the microcontroller or digital circuitry, ensuring a controlled start-up state after power-up or brownout conditions.

Manual Reset Input

ADM811ZART-REEL includes a manual reset input (MR) that allows an external signal to force a reset condition.

Advantages and Disadvantages

Advantages

• Reliable voltage monitoring and reset functionality
• Low power consumption
• Wide operating voltage range
• Small package size

Disadvantages

• Limited reset timeout period options
• Lack of additional advanced features

Working Principles

ADM811ZART-REEL operates by comparing the supply voltage with the preset threshold voltage. If the supply voltage falls below the threshold, the reset output is activated. The reset remains active until the supply voltage rises above the threshold or a manual reset signal is applied.
