SYSTEM AND METHOD FOR EXTENDING THE USB POWER SIGNAL
摘要
<p>A system and method for extending the USB VBUS power signal. A system for extending the USB VBUS power signal includes at least one PCA board. The system includes a USB host. The USB host outputs a new power signal compliant with USB VBUS power signal requirements. The VBUS signal may be connected to a voltage converter to change the voltage level to a desired enable signal for the voltage supply at the receiving end of the system. The VBUS signal may be connected to logic to change the polarity of the enable signal. The enable signal is routed across traces on the one or more PCA boards. A voltage supply is located on a PCA board and receives the enable signal. The enable signal causes the voltage supply to output a new power signal that is compliant with USB VBUS power signal requirements.</p>
