Functional Features

Voltage Detection

S-80854CNNB-B9FT2U can accurately detect the voltage level applied to its input pin within the specified range.

Reset Function

When the detected voltage falls below the threshold, the S-80854CNNB-B9FT2U generates a reset signal on its output pin, indicating the need for a system reset.

Manual Reset

The MR pin allows for manual reset functionality, enabling users to initiate a reset manually when required.

Delay Circuit

The built-in delay circuit ensures that the reset signal remains stable for a specific duration (typically 200ms) after the voltage returns to the normal operating range.

Advantages and Disadvantages
