Hand-held devices require communication with the notebook PC before they start to draw current. This ensures that the handheld device will obtain sufficient current when it wants to charge. The issue is that the notebook PC does not have a way to provide this acknowledge signal to the handheld device when the notebook is in “Sleep” mode. Pericom’s PI5USB14550-A solves this issue by setting the D+/ D- pins in the notebook PC to the required signal levels during “sleep” mode. When the handheld device sees these required signal levels, it will then start to draw the current required to charge itself. Cell phones within today’s market use different communication schemes, therefore the switch will need to configure itself in different modes. PI5USB14550-A can alternate between modes automatically, once device type is correctly detected.
