Advance Information
Mini or Micro-USB Interface IC
The 34827 is a dedicated IC for managing charging and signal
multiplexing between a cell phone and its accessory via a 5-pin Mini or
Micro-USB connector. An external power source, such as a dedicated
AC/DC adapter or a standard USB port, is able to charge the battery in
the cell phone via the connector. The 34827 is capable of identifying
the type of the external power source and selecting one of two battery
charge current levels according to the type. The internal power switch
can protect the phone system against 28 V power supply input. The
34827 is also able to multiplex the 5 pins to support UART and High-
Speed USB 2.0 data communication, mono/stereo-audio/microphone
headset with or without a cord remote control, manufacturing or R/D
test cables and other accessories.

INTERFACE IC
To identify what accessory is plugged into the Mini or Micro-USB
connector, the 34827 supports various detection mechanisms,
including the VBUS detection and ID detection. A high accurate 5-bit
ADC is offered to distinguish the 32 levels of ID resistance and to
identify the button pressed in a cord remote control while an Audio

ORDERING INFORMATION
34827 configures itself to support the accessory and interrupts a host
via an I 2 C serial bus for further actions. The 34827 is also able to
identify some non-supported accessory, such as video cable, Phone-
Powered Devices and USB OTG devices. The host controls the 34827
via the I 2 C serial bus.
