This motor driver reduces switching noise of the output current and enables for smooth motor rotation. 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 Dimension (Units:mm) 6.5–0.2 20 11 1 10 0.65 0.22–0.1 0.3Min. 0.1 SSOP-B20 Applications CD, MD Absolute Maximum Ratings (Ta=25˚C) Parameter Symbol Limits Power supply voltage Power dissipation VCC Pd 7 800 * Operating temperature range Topr –30 ∼ +80 Storage temperature range Tstg –55 ∼ +150 Output current IOMAX 700 * Derating: 6.4mW/˚C for operation above Ta=25˚C.
