Atmel® Corporation, the renowned organization in designing and manufacturing of microcontrollers and advanced logic announced here today of the ease of use of the ATR0881 laser diode driver IC for an effectual utilization in combined HD-DVD/Blu-ray, DVD, and CD drives. It has also come out from the proclamation that the ATR0881 has been accommodated in a 4 mm x 4 mm QFN24 package and is also the smallest laser diode driver solution in the whole industry. Furthermore it has been specially deigned to be appropriated for the small slim drives that are exercised rampantly in notebook computers in addition to for half-height drives in the desktop PCs along with consumer DVD recorders.

Atmel, founded in 1984, is a renowned leader in the design and manufacture of microcontrollers, advanced logic, mixed-signal, nonvolatile memory and radio frequency (RF) components. The company through influencing one of the industry's broadest intellectual property (IP) technology portfolios, has been able to provide the electronics industry with complete system solutions. It is recorded as one of the minority elite new companies who are capable of incorporating dense nonvolatile memory, logic and analog functions on a single chip. The Atmel chips are manufactured through the usage of the most advanced wafer processes that includes BiCMOS, CMOS and Silicon Germanium (SiGe) technologies. It is also found to be concentrating on consumer, industrial, security, communications, computing and automotive markets.

From the Company's officials it has been learnt that the ATR0881's QFN housing has been artistically designed and a lead-free paddle-up package in association with the exposed paddle on top for the mere improvement of the heat dissipation. Till now the devices that were readily available in the market had a structural problem with a bottom-located exposed paddle and was a regular feature in the standard QFN packages resulting in the emergence of great difficulties for the sake of the general absence of approachability for the circuit design, for the most part in the optical pick-up products. The Company is confident that the striking absence of this design restriction in it's ATR0881 will be appreciated by the clientele at large. It is to be noted that though the ATR0881 is consisted of 3 outputs for the connection of 3 laser bodies, viz. – a blue (HD-DVD/Blu-ray), a red (DVD), and an infrared (CD), it can be fitted into the same small 24-pin package that get utilized by the renowned laser diode drivers of the Atmel for the sake of two-output combined DVD and CD drives.
