Description
Notebook PCs are used around the world to charge battery-powered
handheld devices such as cell phones and MP3/MP4 players. 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 PI5USB56 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 differ-
ent modes. PI5USB56 can alternate between modes automatically,
once device type is correctly detected.
All signal pins are protected with Pericom’s ESD protection circuits
supporting ESD damage as high as 4kV contact per IEC61000-4-2
Level 2 specification.
Features
Enables USB device to draw current from Vbus when USB
enumeration is not available
Protects USB path from direct shortage to Vbus
Provides full ESD support on exposed I/O pins per IEC61000-4-
2 specification up to level 2 (±4kV contact)
Provides multiple modes of charging to ensure all of the
following spec's can be met:
USB 1.0 charger spec, USB 1.1 charger spec, and YD/T-1591
charger spec
Certain modes available can also support devices using
non-standard approach to charging, such as Apple
products.
The following devices have been proven to be supported
with at least one of the PI5USB56 charging modes.
→ Nokia, Samsung, LGE, HTC, Blackberry, Apple
iPod, Apple iPhone, China models, Palm Pre
Automatically switch between modes by detecting correctly
plugged in device
5V power supply
Ability to enable/disable external power switch when charging
is not required
Low power consumption to support Energy Star Compliance
