LB1813M

The LB1813M is designed as one kind of three-phase, full-wave spindle motor driver IC that features digital speed control, making it ideal for use in 3.5-inch floppy disk drives. This deivce can be used in most disk drives without requiring any output electrolytic capacitors. And this device incorporates a start / stop control input, a revolution detector, hall-effect transducer amplifiers with ADC, thermal protection and index delay circuits, and a single-sided hysteresis index comparator.

Features of the LB1813M are:(1)three-phase, full-wave motor driver;(2)digital speed control;(3)start / stop control input;(4)revolution detector;(5)hall-effect transducer amplifiers with AGC;(6)thermal protection circuit;(7)current limiter circuit;(8)single-sided hysteresis index comparator;(9)index delay circuit;(10)4.2 to 6.5 V supply;(11)36-pin MFP.

The absolute maximum ratings of the LB1813M can be summarized as:(1)supply voltage: 7.0 V;(2)output current: 1 A;(3)power dissipation: 1000 mW;(4)operating temperature range: -20 to +80 ;(5)storage temperature range: -40 to +150 .
