Transcription

1 s Features ÎÎManages communication to allow charging to occur from 2 USB ports ÎÎProvides multiple modes of charging to ensure all of the following specs can be met: BC.0,., &.2 spec YD/T - 59 Chinese Telecom Standard Samsung fast charging Sony Ericsson fast charging Apple fast charging A and 2A Amazon Kindle Fire Certain modes available can also support devices using non standard approaches to charges such as Apple products like iphone, ipod and ipads. ÎÎPatented Automatic USB Device Identification Circuit (used to determine charging mode required) Πα4kV High ESD contact Protection on D+/D- per IEC specification ÎÎ-40ºC to + 85ºC Operating Temperature Range ÎÎPackaging (Pb-free & Green available): 20-pin QSOP (Q) 20-contact TQFN Applications ÎÎLaptops, Netbooks ÎÎUniversal Chargers (Wall, solar, cigarette) ÎÎAutomotive Description USB ports have become the charging connector of choice for the majority of handheld devices such as MP3 players, Mobile phones, MP4 players, DSC, and even tablet/slate type devices. Although the mechanical connector has converged such that these handheld devices can charge using the same cable, the communication scheme followed by each USB device is different when it comes to setting up a charging link. Pericom s PI5USB268 solves the multiple communication protocol problem by supporting all protocols available in the market. Therefore, regardless of what USB device is connected to a charger enabled by Pericom, the USB device will be able to understand the charging setup communication and in turn the USB device will be able to efficiently draw current to charge itself.
