Working Principles
The ADM8321WAX30ARJZR7 operates by continuously monitoring the supply voltage using an internal voltage reference and comparator. When the supply voltage falls below the programmed threshold, the reset output is asserted, indicating a low-voltage condition. The reset output remains active until the supply voltage rises above the threshold and the reset timeout period elapses.
