Working Principles

The S-8261ACFMD-G4FT2U is a low voltage detector IC that continuously monitors the supply voltage. When the voltage drops below the preset detection threshold, the output pin (OUT) is activated. The delay time setting (SET) allows users to adjust the time it takes for the output signal to be triggered after the voltage falls below the threshold. This feature is useful in preventing false alarms caused by temporary voltage fluctuations. The IC operates within a wide voltage range and consumes minimal current in standby mode, making it suitable for various power management applications.
