It accepts a Step/Direction interface and delivers up to 1.5 A per bridge across a load supply range of 4.5 V to 48 V. With >256 microsteps of resolution, it suits precision positioning in general-purpose industrial motion — pick-and-place, lab automation, and small conveyor drives. The -40°C to 125°C operating range covers factory-floor and outdoor cabinet environments without derating. ## No external MOSFETs — BOM simplification Because the DRV8436RGER integrates the Power MOSFETs, there is no external FET stage to select, match, or heat-sink. The two half-bridge outputs directly drive the two phases of a bipolar stepper — the only external components are the supply decoupling caps, current-sense resistors (if using chopper regulation), and the Step/Direction logic signals. This cuts the BOM count and board area versus a discrete FET-plus-gate-driver approach. ## Active lifecycle — no near-term LTB risk The DRV8436RGER is listed as Active with ROHS3 compliance. There is no announced end-of-life or last-time-buy window. For new-design qualification, this part is safe to freeze into a BOM without an obsolescence watch — though TI occasionally shrinks lead times on older nodes, so dual-sourcing with a pin-compatible alternate (if one exists) is a routine risk practice. No official successor exists because none is needed. ## Sourcing posture The DRV8436RGER is sourced through independent distribution channels. The part is not subject to allocation or long lead-time constraints typical of some TI stepper drivers — lead time is evaluated per order, not quoted here. For a BOM line that needs a reliable supply of active stepper drivers, this part qualifies without LTB risk.","metaTitle":"TI DRV8436RGER Stepper Driver, 1.5 A, 48 V","metaDescription":"DRV8436RGER from TI: fully integrated bipolar stepper driver, 1.5 A per bridge, 4.5–48 V load, >256 microsteps, -40 to 125°C.

This is the package-level limit, not per-pin; adequate PCB thermal management is required to sustain the full current at elevated ambient temperatures."},{"question":"Does DRV8436RGER require external MOSFETs?","answer":"No. The DRV8436RGER integrates the Power MOSFET output stage. The two half-bridge outputs directly drive the bipolar stepper motor phases — no external FETs or gate drivers are needed."},{"question":"Is DRV8436RGER compatible with 48 V stepper motors?","answer":"Yes. The load supply voltage range is 4.5 V to 48 V, so 48 V stepper motors are within the rated operating range. Derate the output current per the thermal curve above 40°C to stay within the 125°C junction limit."},{"question":"What is the difference between DRV8436RGER and DRV8825?","answer":"The DRV8825 is a similar TI bipolar stepper driver but with a higher per-bridge current rating (2.5 A typical) and a lower maximum microstep resolution (1/32 step). The DRV8436RGER offers >256 microsteps for smoother low-speed motion and a smaller 4x4 mm VQFN package, but at a lower 1.5 A continuous rating. The DRV8825 also has a wider operating temperature range (-40°C to 150°C) versus the DRV8436RGER's -40°C to 125°C. Choose the DRV8436RGER for finer microstepping and compact layout; choose the DRV8825 for higher torque and higher ambient temperature capability."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/DRV8436RGER","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/DRV8436RGER when reusing this data.
