Overview

The LB1656 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.

特性 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.
