Product details

Integrated stepper driver for 48 V bipolar motors

The Texas Instruments DRV8436RGER is a fully integrated bipolar stepper driver that packs the control logic and Power MOSFET output stage into a single 4x4 mm package. 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.

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.

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 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.

Frequently asked questions

What is the maximum output current of DRV8436RGER?

The DRV8436RGER is rated for 1.5 A continuous per half-bridge. This is the package-level limit, not per-pin; adequate PCB thermal management is required to sustain the full current at elevated ambient temperatures.

Does DRV8436RGER require external MOSFETs?

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.

Is DRV8436RGER compatible with 48 V stepper motors?

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.

What is the difference between DRV8436RGER and DRV8825?

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.
