Press Release Summary:
Lead-free 3-channel AAT4295 supports use of single RGB LED while 6-channel AAT4297 supports systems with 2 RGB LEDs. State of each output channel is controlled with single GPIO line via the EN/SET pin using S2Cwire(TM) serial digital interface, eliminating need for multiple discrete devices. Rated over -40 to +85°C temperature range, products consume less than 3 µA of quiescent current. AAT4295 is available in 2.0 x 2.1 mm 8-pin SC70JW, and AAT4297 is offered in 12-pin TSOPJW package.

AnalogicTech Announces Two New RGB Controllers
Integration Simplifies Design of RGB Diode Sequencing for Mobile Phones
SUNNYVALE, Calif., March 13 / -- 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.
