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 control two DC motors.
L6258EX 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.
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.Key Features
- TTL/CMOS compatible inputs
- No need for recirculation diodes
- Thermal shutdow
- Able to drive both windings of a bipolar stepper motor or two DC motors
- Wide voltage range: 12V to 40V
- Output current up to 1.5A each winding
- Precision PWM control
- Cross conduction protection
- Four quadrant current control, ideal for microstepping and DC motor control
