Working Principles

The TL7705ACDRE4 operates by continuously monitoring the input voltage (VIT) against the set threshold voltage. When the input voltage falls below the threshold, the reset output (RESET) is activated, indicating a power failure or an out-of-range condition. The reset signal remains active until the input voltage rises above the threshold and the reset timeout period elapses.
