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 operating temperature range of -40°C to 125°C covers unventilated enclosures on a factory floor or outdoor telecom pedestals. ## 48 V supply, 2.5 A output — what that means for your motion axis 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. ## Lifecycle and compliance — active, no obsolescence risk ROHS3 compliance covers the EU RoHS exemption list; no lead or restricted-substance issues for global shipping.","metaTitle":"DRV8434PRGER Stepper Motor Driver, 48V 2.5A, TI","metaDescription":"TI DRV8434PRGER bipolar stepper driver, 4.5V-48V supply, 2.5A output, PWM interface, -40 to 125°C, 24-VQFN.

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."},{"question":"Is the DRV8434PRGER compatible with 24V systems?","answer":"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."},{"question":"What is the difference between DRV8434PRGER and DRV8434P?","answer":"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."},{"question":"What is the closest functional second-source to the DRV8434PRGER?","answer":"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."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/DRV8434PRGER","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/DRV8434PRGER when reusing this data.
