Working Principles

The S-8261ACDMD-G4DT2G is a low voltage detector IC that monitors the input voltage and provides an output signal when it falls below a certain threshold. It incorporates a delay time function, allowing users to set a specific delay before the output signal is activated. This feature helps prevent false alarms caused by temporary voltage fluctuations.

The IC operates by comparing the input voltage with the internally set detection voltage. When the input voltage drops below this threshold, the output signal is triggered. The delay time can be adjusted using external capacitors connected to the CTI pin. Once the delay time elapses, the output signal becomes active.
