Working Principles

The TPS3850G30QDRCRQ1 operates by continuously monitoring the input voltage and comparing it to the programmable threshold voltage. If the input voltage falls below the threshold voltage for a specified time period, the reset output is activated. The time delay feature ensures that momentary voltage fluctuations do not trigger false resets.
