L6258EP(2005) 数据手册 ( 数据表 ) - STMicroelectronics

DESCRIPTION
L6258EP 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.
L6258EP 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.

FEATURES
■ ABLE TO DRIVE BOTH WINDINGS OF A BIPOLAR STEPPER MOTOR OR TWO DC MOTORS
■ OUTPUT CURRENT UP TO 1.3A EACH WINDING
■ WIDE VOLTAGE RANGE: 12V TO 40V
■ 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
