Micro-USB Interface IC
Supporting Universal Charging
Solution and Wired Accessories
The 34825 is designed to support the Universal Charging Solution
(UCS) recommended by the OMTP (Open Mobile Terminal Platform),
as well as to use the same 5-pin micro or mini-USB connector for other
wired accessories. The 34825 supports various types of external power
supplies to charge the battery, such as a dedicated AC/DC adapter or
a USB port. It has functions built-in to identify the type of the power
supply, and sets low or high charging current, based on the current
capability of the power supply. The 34825 monitors the power supply,
and offers an up to 28
V of overvoltage protection (OVP) to the cell
phone against failed power supplies. The 34825 also contains analog
switches to multiplex the five pins, to support UART and high speed
USB data communication, mono or stereo audio headset with or without
a microphone and a cord remote controller, manufacturing or research-
and-development (R/D) test cables, and other accessories.
The 34825 monitors both the VBUS status and the resistance
between the ID pin and the ground to identify the accessory being
plugged into the mini or micro-USB connector. A high-accuracy 5-bit
ADC is offered to distinguish 32 levels of ID resistance that are
assigned to buttons in a cord remote controller or to identification (ID)
resistors of accessories. After identifying the attached accessory, the
34825 sends an interrupt signal to a host IC and the host IC can
configure the analog switches via an I
2
C serial bus for further actions.
When the accessory is detached from the cell phone, an interrupt signal
is also sent to inform the host. This device is powered using
SMARTMOS technology.

charging current levels
