PI5USB2058
Description
Notebook PCs are used around the world to charge battery-pow-
ered 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. is ensures that the hand-
held device will obtain sucient current when it wants to charge.
e issue is that the notebook PC does not have a way to provide
this acknowledge signal to the handheld device when the note-
book is in “Sleep” mode.
Pericom’s PI5USB2058 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 dierent communication
schemes, so the switch will need to congure itself in dierent
modes. PI5USB2058 can alternate between modes automatically,
once device type is correctly detected.
D+, D- and Vbus pins are protected with Pericom’s ESD protec-
tion circuits supporting ESD damage as high as +/-8kV contact
per IEC61000-4-2 specication.
