Product details

What this driver does on your board

The Texas Instruments DRV8434PRGER is a fully integrated bipolar stepper motor driver that combines control logic and power stage in one package. It drives one bipolar stepper motor or two brushed DC motors using a PWM interface, with each half-bridge rated for 2.5 A continuous output. The supply range spans 4.5 V to 48 V. The internal Power MOSFET stage eliminates the need for discrete FETs and freewheeling diodes on the motor outputs, shrinking the BOM for a compact drive stage.

The half-bridge (2) output configuration means two full H-bridges are integrated internally, one per winding for a bipolar stepper. Each bridge handles the full 2.5 A, so no external current-sense resistors or recirculation diodes are needed — the part manages the current regulation cycle internally via the PWM interface.

ROHS3 compliance covers the EU RoHS exemption list; no lead or restricted-substance issues for global shipping.

Frequently asked questions

Can the DRV8434PRGER drive a 48V bipolar stepper motor at 2.5A?

Yes. The part is rated for a 4.5 V to 48 V supply and 2.5 A continuous output per winding. It is designed specifically for bipolar stepper motors, so a 48 V stepper at 2.5 A is within its operating envelope.

Is the DRV8434PRGER compatible with 24V systems?

Yes — the 4.5 V to 48 V supply range includes 24 V. The part will run a 24 V bipolar stepper or brushed DC motor without any modification. The 2.5 A current rating is independent of supply voltage within that range.

What is the difference between DRV8434PRGER and DRV8434P?

The DRV8434PRGER and DRV8434P share the same core driver function and ratings. The suffix difference typically indicates packaging or tape-and-reel variant — the PRGER is in Tape & Reel (TR) and Cut Tape (CT) formats, while the P variant may be in a different reel quantity or tube. Functionally they are the same silicon.

What is the closest functional second-source to the DRV8434PRGER?

The DRV8811PWPR from TI is a similar fully integrated bipolar stepper driver, but it has a lower output current rating of 1.9 A and a different package (HTSSOP). It is not a pin-compatible drop-in — the DRV8434PRGER offers higher current (2.5 A) and a smaller 4×4 mm VQFN footprint. For a 2.5 A design, the DRV8434PRGER is the correct choice.
