AnalogicTech Announces Two New RGB Controllers

AnalogicTech Announces Two New RGB Controllers

March 13, 2006

Integration Simplifies Design of RGB Diode Sequencing for Mobile Phones

    SUNNYVALE, Calif., March 13 /Xinhua-PRNewswire/ --
Advanced Analogic Technologies Incorporated (AnalogicTech)
(Nasdaq: AATI), a developer of power management
semiconductors for mobile consumer electronic devices,
today announced the highly integrated AAT4295 and AAT4297
RGB controllers.  Targeted at portable systems, the two new
controllers dramatically simplify the design and layout of
fashion lighting functions by eliminating the need for
multiple discrete devices while saving valuable GPIO
resources.

    To generate the three colors in an RGB LED, designers
must typically sequence the diodes and control the current
going to each separate red, blue, and green diodes within
the package. "Designers would typically need to use
three separate MOSFETs, all the associated interface
circuitry, and three GPIO pins on the system processor to
drive the RGB LED," explains Phil Dewsbury, Product
Line Director for AnalogicTech. "With the AAT4295 and
AAT4297, designers can now support up to two RGB LEDs while
eliminating the need for discrete MOSFETs and save the GPIO
lines for other system functions."

    Three, Six-Channel Versions

    The three-channel AAT4295 supports the use of a single
RGB LED while the six-channel AAT4297 supports the design
of systems with two RGB LEDs.  The state of each output
channel is controlled with a single GPIO line via the
EN/SET pin using AnalogicTech's Simple Serial Control(TM)
(S2Cwire(TM)) serial digital interface.  Both the AAT4295
and the AAT4297 can also be used for general-purpose
applications whenever a load requires a low-side switch
connection to ground. 

    The AAT4295 and AAT4297 operate over a 1.8V to 5.5V
input range.  Both devices consume less than 3uA of
quiescent current. 

    Price and Availability

    Rated over the -40 degrees C to +85 degrees C
temperature range, the AAT4295 and AAT4297 are available
now.  The AAT4295 is offered in a tiny (2.0x2.1mm) Pb-free,
8-pin SC70JW package and sells for $0.71 in 1,000-unit
quantities. The AAT4297 is offered in a Pb-free, 12-pin
TSOPJW package and sells for $0.90 in 1,000-unit
quantities.
