LB1656

The LB1656 is designed as one kind of 2-phase stepping motor driver that is suited for use for FDD (3 to 5.25 inches) head actiator. The maximum driver current x voltage is 0.33 A x 12 V / bridge.

Features of the LB1656 are:(1)power save function;(2)1,2 irection inputs are used to make driver output selection;(3)low saturation voltage;(4)low current dissipation;(5)direct controllable from MPU due to low input current;(6)input level: TTL, LSTTL, 5V CMOS compatible;(7)on-chip thermal shutdown (TSD) circuit.

The absolute maximum ratings of the LB1656 can be summarized as:(1)logic section supply voltage: 7 V;(2)seeking supply voltage: 15 V;(3)holding supply voltage: 7 V;(4)input voltage: 0 to Vcc V;(5)peak seeking current: 500 mA;(6)continuous seeking current: 330 mA;(7)hloding current: 200 mA;(8)allowable power dissipation: 1.9 W;(9)operating temperature: -20 to +70 ;(10)storage temperature: -55 to +125 .
