1 / 12 page 3-Phase Brushless Motor Driver for CD-ROM Spindle Motors Overview The LB1895 and LB1895D are 3-phase brushless motor drivers for use in CD-ROM spindle motors. Functions and Features . Current linear drive . V-type control amplifier built in . Because the power supply for the bias circuit on the upper output side is separate, output with low saturation can be attained by boosting only that power supply. (Effective when VCC =5 V) . Because current is detected on the upper side, there is no voltage loss due to the RF resistance. In addition, the RF voltage reduces the power dissipation within the IC. (Effective when VCC =5 V) . Start/Stop function built in . Thermal shutdown circuit built in . Overcurrent protection circuit built in . Two-channel Hall signal comparator built in. (For detecting rotation direction and Hall FG output) . Hall device bias built in Package Dimensions unit : mm 3222-HSOP28 [LB1895] 114 0.3 0.8 15 28 2.7 15.2 0.8 0.2 SANYO : HSOP28 unit : mm 3196-DIP30SD [LB1895D] SANYO : DIP30SD Ordering number: EN5634 Monolithic Digital IC LB1895, 1895D SANYO Electric Co.,Ltd.
