Fairchild’s FAN8741 Motor Driver IC Selected by TSST
Fairchild Semiconductor International (South Portland, ME) announced that Toshiba-Samsung Storage Technology (TSST) has chosen Fairchild's seven-channel, motor driver IC for its high-end, DVD-RW product. With its low-output, on-resistance (spindle 0.8 ohms at 0.5 A, sled 2.0 ohms at 0.25 A), the IC reduces heat generation, which is an important consideration in DVD-RW designs where thermal management is an ongoing challenge.
In tests conducted using a brushless dc motor running at 10,000 rpm with 3.3 V, the temperature of Fairchild's FAN8741 was over 20 °C lower than competitive products. The FAN8741's built-in thermal shutdown and power packaging extends reliability in high-speed, optical media applications. The motor driver IC eliminates the need for additional components and lowers overall design costs.
"The versatility and reliability of the FAN8741 make it ideal for use in TSST's new DVD-RW product, the TS-H552, which is capable of writing up to 16X on a DVD+R disc," commented TSST Korea President IS Hwang. "In this rapidly evolving optical disc drive market, TSST must respond quickly to changing demands. Fairchild's superior engineering support, volume production and quality of service allow us to deliver value to the market in a timely fashion."
The FAN8741 is available in a 56-SSOP package. The lead-free product meets or exceeds the requirements of the joint IPC/JEDEC standard J-STD-020B, and is compliant with the European Union requirements, which will take effect in 2005. Pricing for the FAN8741 is $2.51 for 1,000-piece quantities. Available now, delivery is 12 weeks from ARO.
