That 1A figure is the current the internal Power MOSFETs can sustain without thermal shutdown at the rated ambient — derate it if the board runs above 85°C or if the 16-WQFN (3x3 mm) pad isn't getting a good copper pour for heat sinking. The step/direction interface keeps the motion-control firmware simple — one pulse per step, no SPI or UART setup. ## Step resolution and motor types it handles With >256 microsteps per full step, the DRV8428RTER delivers smooth low-speed rotation and reduces mid-frequency resonance — useful for positioning stages, 3D printer axes, or any application where audible noise and vibration matter. The driver supports bipolar stepper motors, brushed DC motors, and brushless DC (BLDC) motors through its two half-bridge outputs. The half-bridge configuration (2 outputs) means it drives a single bipolar stepper as a full H-bridge per winding, or two brushed DC motors independently. For a BLDC motor you'd need external commutation logic — the driver itself doesn't sequence the phases. ## Active production and compliance documentation The part is ROHS3 compliant, so it meets the latest EU restriction directive without exemption. No UL or IEC certification is cited in the available documentation; for safety-critical designs, verify with the full datasheet. The package options are Tape & Reel (TR) for automated pick-and-place and Cut Tape (CT) for prototyping or low-volume builds.","metaTitle":"Texas Instruments DRV8428RTER Stepper Motor Driver, 1A, 33V","metaDescription":"Texas Instruments DRV8428RTER bipolar stepper motor driver, 1A output, 4.2V to 33V supply, >256 microsteps.
