LB1650

The LB1650 is designed as one kind of dual bidirectional motor driver. Since each channel has a 2-input logic circuit and performs bidirectional driving and braking functions, it is capable of direct driving 2 pcs. of motor of various types rated at 6 to 24 V. The output voltage can be varied by using external zener diodes. It is especically suited for dual motor drive (reel motor, loading motor, cassette motor in VTR) and for stepping motor drive.

Features of the LB1650 are:(1)with power transistors for motor drive contained, capable of withstanding dash current of 1 A max;(2)performs braking function at the motor stop mode;(3)contains elements to absorb motor dash current;(4)input connectable direct to MOS LSI;(5)minimum number of external parts required;(6)wide operating voltage range.

The absolute maximum ratings of the LB1650 can be summarized as:(1)maximum supply voltage: 36 V;(2)input current: 36 V;(3)output current: 2 A;(4)allowable power dissipation: 1.9 W;(5)operating temperature: -25 to +80 ;(6)storage temperature: -40 to +150 .
