Additional Infomation About Product

L6258EA 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 1.5A each winding Wide voltage range: 12V to 40V Four quadrant current control, ideal for microstepping and dc motor control Precision PWM control PowerSO36 No need for recirculation diodes TTL/CMOS compatible inputs Cross conduction protection Thermal shutdow The power stage is a dual DMOS full bridge Extended low operating temperature range: capable of sustaining up to 40V, and includes the -40C 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 Description protection circuitry disables the outputs if the chip temperature exceeds the safe limits. 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. Table 1.
