1.5 A bipolar stepper driver with integrated FETs
The Texas Instruments DRV8885RHRR is a fully integrated bipolar stepper motor driver that combines the control logic and NMOS power stage in a single 28-WFQFN package with exposed pad. It drives one bipolar stepper motor at up to 1.5 A continuous output current from an 8 V to 37 V load supply rail.
Microstepping and thermal range
Step resolution is programmable from full-step down to 1/16 microstep via the logic-level interface, which lets the designer trade torque ripple against positioning smoothness without changing the motor.
