■ TTL/CMOS compatible inputs
■ Cross conduction protection
■ Thermal shutdow
■ Extended low operating temperature range:
-40°C
Description
L6258EA 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.
L6258EA 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.
PowerSO36
The power stage is a dual DMOS full bridge
capable of sustaining up to 40V, and includes the
diodes for current recirculation.The output current
capability is 1.5A per winding in continuous mode,
with peak start-up current up to 2A. A thermal
protection circuitry disables the outputs if the chip
temperature exceeds the safe limits.
