It drives one bipolar stepper motor at up to 2.5 A per phase from a load supply of 4.5 V to 33 V. The Step/Direction interface accepts external pulse trains, and the step resolution is programmable from full-step down to 1/256 microstepping, giving smooth low-speed motion and reducing mid-range resonance. ## Load voltage and current — sizing the power rail The 2.5 A continuous output per phase is the peak current the H-bridge can sustain; the actual motor current should be set via the chopper reference to stay within the package's thermal limit at the ambient temperature. The internal Power MOSFETs eliminate the need for external FETs and freewheeling diodes in most designs, reducing BOM count and PCB area. The half-bridge (2) output configuration drives a single bipolar stepper winding per bridge. Available in Tape & Reel (TR) and Cut Tape (CT) options, the part is compatible with automated pick-and-place assembly. The surface-mount package suits high-volume production lines. ## Active production — sourcing posture It is sourced through authorized and independent distribution channels; pricing and lead time are confirmed at RFQ against the specific BOM quantity.","metaTitle":"DRV8424PWPR Stepper Driver, 2.5A, 4.5-33V, 28-HTSSOP","metaDescription":"Texas Instruments DRV8424PWPR bipolar stepper motor driver, 2.5A output, 4.5-33V load, 1/256 microstepping, 28-PowerTSSOP.
