USB Host Charger Controller supporting BC1.2,
YD/T-1591, & non-standard protocols
Features
Description
Notebook PCs are used around the world to charge battery-pow-
ꢀÎManages communication to allow charging to occur
ꢀÎProvides multiple modes of charging to ensure all of the
ered handheld devices such as cell phones, tablets and MP3/MP4
players. Hand-held devices require communication with the
notebook PC before they start to draw current. is ensures that
the handheld device will obtain sufficient current when it wants
to charge. e challenge is that notebook PC's do not provide
acknowledge signal to the handheld device when the notebook
is in “Sleep” mode.
following specs can be met:
à DCP, CDP, and SDP per BC1.0, 1.1, 1.2 spec
à DCP per YD/T-1591 spec
à Samsung fast charging
à Sony Ericsson fast charging
à Apple fast charging 1A
à Amazon Kindle Fire
ꢀÎAutomatic USB Device Identification Circuit (used to
determine charging mode required)
ꢀÎSingle Power Supply, 5V 5%
ꢀÎ-40oC to +85o C Operating Temperature Range
Pericom’s PI5USB1468(/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.
ꢀÎIntegrated ESD protection up to +/- 4kV contact on pins
Cell phones within today’s market use different communication
schemes, so the switch will need to configure itself in different
modes. PI5USB1468 (/A) can alternate between modes automati-
cally, once device type is correctly detected.
2 and 3 per IEC61000-4-2 spec
ꢀÎDetects and differentiates between High-Speed devices and
mouse/keyboard (USB Low/Full Speed device) when in Auto
dedicated charging mode
ꢀÎAnti-loop protection for hard disk drive (HDD)
ꢀÎPackaging (Pb-free & Green):
D+, D- are protected with Pericom’s ESD protection circuits sup-
porting ESD damage as high as +/-4kV contact per IEC61000-4-2
specification.
