Functional Features

Voltage Monitoring

ADM1232ANZ continuously monitors the supply voltage and compares it with a user-defined threshold voltage. When the supply voltage falls below this threshold, the IC triggers a reset signal.

Reset Function

The IC provides a reliable reset signal to ensure that the microcontroller or other digital circuitry starts in a known state after power-up or brownout conditions. This helps prevent unpredictable behavior and data corruption.

Adjustable Threshold Voltage

The threshold voltage for triggering the reset signal can be adjusted using external resistors. This flexibility allows customization based on specific application requirements.

Programmable Reset Timeout Period

ADM1232ANZ offers the ability to program the reset timeout period using an external capacitor. This feature enables fine-tuning of the reset duration according to the needs of the system.

Advantages and Disadvantages

Advantages

• Reliable voltage monitoring and reset functionality
• Low power consumption
• Wide operating voltage range
• Customizable threshold voltage and reset timeout period

Disadvantages

• Limited number of pins for additional functionalities
• Requires external components for threshold voltage and reset timeout adjustment

Working Principles

ADM1232ANZ operates by continuously monitoring the supply voltage through the VCC pin. It compares the voltage with the user-defined threshold voltage set using external resistors. When the supply voltage falls below this threshold, the IC triggers a reset signal by pulling the RESET pin low.

The reset signal remains active until the supply voltage rises above the threshold and the reset timeout period, set using an external capacitor, elapses. This ensures that the microcontroller or digital circuitry starts in a known state after power-up or brownout conditions.
