BD6609FV

www.DataSheet4U.com 00W013A Spindle Motor Driver for CD/MD BD6609FV Description 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. 6.4–0.3 4.4–0.2 1.15–0.1 Dimension (Units:mm) 6.5–0.2 20 11 1 10 0.1 0.65 0.22–0.1 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 Power dissipation Operating temperature range Storage temperature range Output current (Ta=25˚C) Limits 7 800 * –30 ∼ +80 –55 ∼ +150 700 (Ta=25˚C) Min. 2.4 Typ. — Max. 6.5 Unit V Unit V mW ˚C ˚C mA VCC Pd Topr Tstg IOMAX for operation above Ta=25˚C.
