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 challenge is that notebook PC's do not provide acknowledge signal to the handheld device when the notebook is in “Sleep” mode. Pericom’s PI5USB1458(/A) solves this issue by setting the D+/D- pins in the notebook PC to the required signal levels dur- ing “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, so the switch will need to configure itself in different modes. PI5USB1458 (/A) can alternate between modes automati- cally, once device type is correctly detected. D+, D- are protected with Pericom’s ESD protection circuits sup- porting ESD damage as high as +/-4kV contact per IEC61000-4-2 specification. 13-0030 |
