Working Principles

The ADM6321BZ25ARJZ-R7 is a voltage supervisor IC that operates by comparing the supply voltage with a fixed threshold voltage. When the supply voltage drops below the threshold, the reset output is asserted low, indicating a power failure or an out-of-specification condition. The reset output remains low until the supply voltage rises above the threshold and the reset timeout period elapses.

Detailed Application Field Plans

• Battery-powered devices: The ADM6321BZ25ARJZ-R7 can be used in portable electronics such as smartphones, tablets, and wearables to monitor the battery voltage and initiate a system reset if necessary.
• Industrial control systems: It can be employed in industrial applications where precise monitoring of power supply voltage is crucial for reliable operation and system protection.
• Automotive electronics: The IC can be utilized in automotive systems to monitor the vehicle's electrical system and ensure proper functioning of critical components.
