Working Principles

The S-8211CCR-M5T1U operates by comparing the input voltage (VDD) with the internally set detection voltage level. When the input voltage falls below or exceeds the detection voltage threshold, the output pin (OUT) changes its state accordingly. The built-in delay circuit ensures a stable output response by introducing a delay of approximately 200ms.

The enable pin (EN) provides control over the output status. By applying a high-level signal to the EN pin, the voltage detection function can be enabled or disabled as needed. This feature allows for power-saving operation when voltage monitoring is not required.
