Royal Philips Electronics (NYSE: PHG, AEX: PHI)
today announced the industry's smallest motor driver IC for high-speed DVD+RW
(DVD+ReWritable) applications. The Philips SA56202 motor driver is approximately
half the size of competing solutions, with a small footprint that is ideal for
such portable consumer and data applications as DVD+RW recorders and data drives
for the PC market. This highly integrated one-chip device has a 3-phase
brushless, hall-commutated spindle driver, 2-channel stepper motor driver, and 4
linear channels for the tray and 3D actuators, providing customers with the
performance needed for high-speed applications while reducing component count
and system cost.
The DVD recorder chip market (in particular) is
expected to grow at a CAGR of 63 percent from 2002 to 2007, according to
industry analyst firm IDC, Feb 2003. To meet the changing performance demands of
this quickly growing market, the SA56202 motor driver has been designed to
support drive speeds of 8x and 16x speeds, offering drive manufacturers a quick
transition to next-generation technology. The SA56202 motor driver is used in
the Philips NexperiaTM reference design for 8x DVD Recordable applications that
facilitate customer design-in and system development, while accelerating time to
market.
"The SA56202 motor driver was selected for our new
DVD+R/+RW data drive architecture because it can deliver the superior
performance we need for current and future products," said Frank Simonis of
Philips Optical Storage. "Based on this architecture, we are able to create new
products quickly with higher write speeds (4x to 8x and above) and stay
competitive in the data drive markets."
At high speeds, thermal management presents a
substantial challenge for designers of portable consumer and data applications.
To overcome this challenge, the patented Philips design integrates active
braking technology - the industry's fastest, most efficient form of braking -
into the SA56202. With active braking in the SA56202, disks can brake from full
speed to a complete stop in a linear, controlled manner. In fact, the SA56202
can brake to a full stop in approximately half the time of competing solutions
(from 11,320 rpm to 0 rpm in only 2.8 seconds). The Philips SA56202 also has a
user-selectable current limiter, to limit thermal dissipation during (fast)
braking. Furthermore, with the Philips device, the braking energy is recuperated
by transferring it back to the power supply, resulting in less heat dissipation
during braking and better overall performance. This is in contrast to competing
drivers that employ "short" braking and dissipate the braking energy into the
driver device itself as heat. This wasted heat in the driver poses a serious
risk of thermal shutdown or breakdown.
The 56-pin HTSSOP Philips motor driver IC has a
footprint of only 6.1mm by 14 mm. To house an IC in a package this small, it is
necessary to use a special process to deliver high performance and small form
factor. By using an advanced BCDMOS (Bi-Polar CMOS DMOS) process, different
aspects of the chips can be optimized - such as delivering the required high
voltage (12V) outputs along with the drive strength and response of the
integrated drivers in a small form factor.

Samples of the SA56202 motor driver are available
now. Volume production is scheduled for August 2003. Please visit www.semiconductors.philips.com for
