Power supply interface

The embodiment of the utility model relates to a power supply interface. The power supply interface includes a first switch coupling an input terminal to an output terminal. The voltage division bridge is coupled to receive a supply potential. The comparator has a first input connected to the first node of the bridge, and a second input configured to receive a constant potential. The digital-to-analog converter generates a control voltage that is selectively coupled to a second node of the bridge through a second switch. The circuit control controls actuation of the second switch based on the operating mode and generates a digital value input to the converter based on a negotiated setpoint of a supply potential applied to the input terminal. The power supply interface according to the embodiment of the present disclosure has the advantage of providing overvoltage protection. 本公开的各实施例涉及供电接口。供电接口包括将输入端子耦合到输出端子的第一开关。分压电桥被耦合以接收供电电位。比较器具有连接至电桥的第一节点的第一输入端、以及被配置为接收恒定电位的第二输入端。数模转换器生成控制电压，该控制电压通过第二开关选择性地耦合到电桥的第二节点。电路控
