MC34825 analog device supports all-passive audio accessories including stereo
signal, microphone and cord remote control 
AUSTIN, Texas--(Business Wire)--
Freescale Semiconductor is introducing a mini USB interface IC that helps mobile
device designers and manufacturers create smaller, sleeker consumer products by
enabling a single mini USB connector for external accessories including
chargers, headsets, microphones and audio/data connections. 

In addition to saving valuable board space by eliminating the need for multiple
connections, the MC34825 analog IC also lowers power consumption and extends
battery life by supporting all-passive audio accessories such as stereo audio,
microphone and cord remote control functionality. 

"The MC34825 leverages Freescale`s 15 years of experience in delivering portable
power management solutions that help our customers differentiate in competitive
consumer electronics markets," said Scott Ward, vice president and general
manager of Freescale`s Analog, Mixed-Signal & Power Division. "This IC helps
consumer device manufacturers give consumers what they want - smaller form
factors and a single connection that eliminates the need for multiple adapters
and cords." 

Applications for the MC34825 include smartbooks, netbooks, eBooks, mobile
phones, smartphones, portable media players, portable navigation devices,
digital still cameras and camcorders. 

The MC34825 uses intelligent switching to identify up to 32 different accessory
types, such as headsets, microphones and chargers. It automatically identifies
the attachment and informs the host system, switching the signal or setting the
charge current based on the plugged-in charger. 

As a universal charging solution, the MC34825 supports multiple charger types
including AC, DC and USB. The IC identifies the battery charger type and sets
the charge current level accordingly. Additional battery charging features
include up to 28V OVP for the VBUS power input, ultra low operating current
(<10uA at standby), a power-save mode and automatic detachment detection. 

Availability and pricing

The MC34825 USB interface IC is available now from Freescale and its
distributors. Suggested resale pricing for the MC34825 is 82 cents (USD) in
10,000-piece quantities.
