PI5USB66
USB Charge Controller IC for Single USB Port
Features
Description
ÎÎManages communication to allow charging to occur
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.
ÎÎProvides multiple modes of charging to ensure all of the
following specs can be met:
àà DCP mode per USB BC1.0, 1.1, & 1.2 spec
àà YD/T - 1591 charger spec
àà Certain modes available can also support devices
using non standard approaches to charges such as
Apple products.
ÎÎAutomatic USB Device Identification Circuit (used to
determine charging mode required)
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 PI5USB66 solves the multiple communication language 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.

Maximum Ratings (Above which the useful life may be impaired. For user guidelines, not tested)
Note:
All Inputs and Outputs...................................-0.5V to VDD +0.5V
Storage temperature................................................... -65 to +150ºC
Ambient Operating Temperature.............................. -40 to +85ºC
Supply Voltage to Ground Potential (VDD).......................... +5.5V
Junction Temperature...........................................................+150ºC
Soldering Temperature (Max of 10 seconds).....................+260ºC
Stresses greater than those listed under MAXIMUM
RATINGS may cause permanent damage to the device. This
is a stress rating only and functional operation of the device
at these or any other conditions above those indicated in
the operational sections of this specification is not implied.
Exposure to absolute maximum rating conditions for
extended periods may affect reliability.
Stress beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
