L6258E PWM controlled high current DMOS universal motor driver Not recommended for new design 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 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 capable of sustaining up to 40V, and includes the Description diodes for current recirculation.The output current capability is 1.2A per winding in continuous mode, L6258E is a dual full bridge for motor control with peak start-up current up to 1.5A. A thermal applications realized in BCD technology, with the protection circuitry disables the outputs if the chip capability of driving both windings of a bipolar temperature exceeds the safe limits. stepper motor or bidirectionally control two DC motors. L6258E 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.
