New LED Driver and Sequencer Launched by Dialog Semiconductor to
Enable Complete Programmability of 18 LEDs
KIRCHHEIM/TECK, Germany--(BUSINESS WIRE)--May 23, 2005--Dialog
Semiconductor Plc (NASDAQ:DLGS)(FWB:DLG):
Single Device Enables Full Control over Individual Brightness and
Sequence of Each LED, without the Need for Dedicated Processing Power
Dialog Semiconductor Plc (NASDAQ:DLGS)(FWB:DLG) has
launched a new universal LED controller which provides complete
programmability of up to 18 LEDs for the control of lightshows,
backlights and signal LEDs in cellular handsets, handheld games, and
other portable devices requiring varying light sequences. The new
DA9026 IC allows the control of sequences of LED patterns including
combined RGB LEDs, with programmable variables such as pattern,
repetition rate and intensity of each LED - this is done entirely
within the device, removing the need for dedicated processing power.
The DA9026 universal LED controller especially addresses the
growing complexity of LED management in applications such as clamshell
handsets, lightshows, backlights (keypad and LCD) and signal LEDs.
This is in response to a growing trend for the display or lights to
flash in appropriate sequences to ringtones, music or different
callers for example. In addition, for phones used in handsfree kits in
the automotive environment, it allows manufacturers to control and
customize the handset backlight to match color and level of
illumination of the car's dashboard display.
Dialog Semiconductor has addressed these needs with this universal
LED driver and sequencer. Unlike other devices it can control up to 18
single color LEDs or six RGB LEDs - or any combination of single and
RGB. It can also store and replay (from on-chip memory) 15 light
sequences with programmable start and end points, without the need for
external components and controlled using a simple 2-wire interface to
upload sequence and command data. A comprehensive PC-based development
tool allows handset manufacturers to create and program the control
code required to generate these sequences.
Other key features include fading and dimming functionality
without the need for baseband processor support, brightness correction
for true RGB color, and an integrated step-up converter to generate
the higher voltages required for high intensity blue, green and white
LEDs. The 4-bit current control enables 4k color options per RGB
channel, and the DA9026 is optimized for lithium battery supplies.
One of the most significant benefits of having everything
contained in one chip and only requiring two-wire control is the
ability to improve reliability in clamshell type cellular handsets -
instead of requiring multiple control lines across the flip mechanism
only two signals are required to control up to 18 LEDs. The DA9026
will typically preload sequence data in the device RAM on power-up,
and then the only communication required subsequently will be to
activate the required sequences.
Another important feature of the DA9026 is its high current
capability, ideal for generating high brightness levels. It can supply
4.8V at up to a maximum of 420mA to provide a regulated power source
for large display configurations of up to 18 LEDs, with consistent
color generation capability for all the LEDs, even as the battery
discharges. When the LED voltage does not need to be greater than 3V,
the LED driver can be directly connected to the battery.
The DA9026 universal LED controller is available now and packaged
in a 24-lead 4 x 4mm QFN package.
A demonstration of the capabilities of the new DA9026 can be seen
at www.vegaschip.net.
