L6258 is a dual full bridge for motor control applications realized in BCD technology, with the capability of driving both windings of a bipolar stepper motor or bidirectionally control two DC motors.
L6258 and a few external components form a complete control and drive circuit. It has high efficiency phase shift chopping that allows a very low current ripple at the lowest current control levels, and makes this device ideal for steppers as well as for DC motors.
The power stage is a dual DMOS full bridge capable of sustaining up to 34V, and includes the diodes for current recirculation. The output current capability is 1.2A per winding in continuous mode, with peak start-up current up to 1.5A. A thermal protection circuitry disables the outputs if the chip temperature exceeds the safe limits.主要特性
