Working Principles

The VN772KP-E utilizes MOSFET technology to control inductive loads. When the input signal at the IN pin is high, the internal MOSFET turns on, allowing current to flow from the VCC pin to the OUT pin, activating the load. Conversely, when the input signal is low, the MOSFET turns off, interrupting the current flow and deactivating the load.
