L6258
PWM controlled
high current DMOS universal motor driver
Features
■ Able to drive both windings of a bipolar stepper
motor or two DC motors
■ Output current up to 1.2A each winding
■ Wide voltage range: 12V to 34V
■ Four quadrant current control, ideal for
microstepping and DC motor control
■ Precision PWM control
■ No need for recirculation diodes
■ TTL/CMOS compatible inputs
■ Cross conduction protection
■ Thermal shutdow
Description
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.
