LB1893

The LB1893 is designed as one kind of 3-phase brushless omtor driver for CD-ROM spindle motors. Features of the LB1893 are:(1)3-phase bipolar brushless motor driver;(2)voltage linear drive, enabling the external capacitance to be reduced;(3)thermal shutdown circuit built-in;(4)overcurrent protection circuit built-in;(5)V-type control amplifier built-in;(6)2-step switchable control gain;(7)control gain switchable using op-amps.

The absolute maximum ratings of the LB1893 can be summarized as:(1)maximum supply voltage: 20 V;(2)output supply voltage: 20 V;(3)output current: 1.2 A;(4)allowable power dissipation: 0.77 W;(5)operating temperature: -20 to +75 ;(6)storage temperature: -55 to +150 .
