Working Principles

The VN770K operates as a high-side switch by controlling the flow of current from the supply voltage to the load. When the input control pin (IN) receives a logic high signal, the switch turns ON, allowing current to flow through the load. Conversely, when the input control pin receives a logic low signal, the switch turns OFF, cutting off the current flow.
