Overview
The LB1656M is a dual bridge driver IC suited for use in 2-phase bipolar stepping motor driver for FDD (3 to 5.25 inches) head actuator.
The maximum driver current×voltage is 0.33A×12V/ bridge.

FEATUREs
• Power save function.
• ø1, ø2 direction inputs are used to make driver output selection.
• Low saturation voltage.
• Low current drain.
• Direct controllable from MPU due to low input current.
• Input level : TTL, LSTTL, 5V CMOS compatible.
• On-chip thermal shutdown (TSD) circuit.
