Description
Notebook PCs are used around the world to charge battery-pow-
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. 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 âSleepâ mode.
Pericomâs PI5USB1458(/A) solves this issue by setting the
D+/D- pins in the notebook PC to the required signal levels dur-
ing âsleepâ 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 todayâs 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 Pericomâs ESD protection circuits sup-
porting ESD damage as high as +/-4kV contact per IEC61000-4-2
specification.
