com 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 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 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.
PowerSO36 Description L6258EX 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 contr...
