00W013A Spindle Motor Driver for CD/MD BD6609FV Description Dimension (Units:mm) The BD6609FV is a CD/MD spindle motor driver employing a 3-phase, full-wave, soft switching, driving system. This motor driver reduces switching noise of the output current and enables for smooth motor rotation. 6.5–0.2 0.1 1 10 0.65 0.22–0.1 0.15–0.1 6.4–0.3 1.15–0.1 11 4.4–0.2 20 0.3Min. 0.1 Features 1) Switching noise reduced due to a soft switching driving system 2) Sensorless driving system allows for a small set design 3) Built-in start, brake, and standby function 4) FG signal output function (with built-in "chatter" prevention circuit) 5) Built-in Thermal Shutdown (TSD) circuit SSOP-B20 Applications CD, MD Absolute Maximum Ratings Parameter Power supply voltage (Ta=25˚C) Symbol Limits Unit VCC 7 V Pd 800 * mW Operating temperature range Topr ˚C Storage temperature range Tstg –30 ∼ +80 –55 ∼ +150 Output current IOMAX Power dissipation * Derating: 6.4mW/˚C ˚C 700 mA for operation above Ta=25˚C.
