Working Principles

The S-80851CLNB-B7CT2U operates based on a voltage divider network connected to the supply voltage. It compares the divided voltage with an internal reference voltage to determine if the input voltage is within the specified range. When the voltage falls below the threshold, the reset output becomes active low, signaling a reset condition.
