Functional Features

Voltage Monitoring

ADM811ZARTZ-REEL7 continuously monitors the supply voltage. When the voltage drops below the specified threshold, it triggers the reset function.

Reset Function

The device generates a reset signal when the supply voltage falls below the threshold. This ensures that the connected microcontroller or digital circuitry starts operating from a known state.

Advantages and Disadvantages

Advantages

• Provides reliable voltage monitoring and reset functionality.
• Low power consumption extends battery life in portable devices.
• Small package size allows for compact designs.
• RoHS compliance ensures environmental safety.

Disadvantages

• Limited reset threshold voltage options may not suit all applications.
• Reset timeout period may not be adjustable, limiting flexibility in certain scenarios.

Working Principles

ADM811ZARTZ-REEL7 utilizes a voltage comparator to monitor the supply voltage. When the voltage drops below the set threshold, the comparator triggers the reset function, generating a reset signal. The reset signal remains active until the supply voltage rises above the threshold again.
