Functional Features

Voltage Detection

S-80840CNMC-B8ZT2U accurately detects the input voltage and compares it with the preset detection voltage. When the input voltage falls below the detection threshold, the reset output is activated.

Reset Output

The reset output provides a signal to reset the electronic device when the input voltage drops below the detection threshold. This ensures proper operation and prevents data corruption or malfunctioning.

Built-in Delay Circuit

This product incorporates a delay circuit that introduces a fixed delay of approximately 200ms before activating the reset output. This delay helps stabilize the system during power-on or voltage fluctuations.
