Product details

Integrated bipolar stepper and brushed DC driver for 8.2–45 V rails

The Texas Instruments DRV8843PWP is a fully integrated motor driver combining control logic and power stage in one 28-pin PowerTSSOP package. It drives one bipolar stepper motor or two brushed DC motors using four internal half-bridges built with Power MOSFETs — no external H-bridge or FETs needed. The supply and load voltage range spans 8.2 V to 45 V, and each half-bridge delivers up to 1.75 A continuous.

1.75 A per channel — sizing the motor load

The 1.75 A output current per half-bridge sets the practical motor winding current. For a bipolar stepper, this gives 1.75 A per phase. For brushed DC, each of the two H-bridges handles 1.75 A continuous.

TI lists the DRV8843PWP as Active (current production) and ROHS3 compliant.

Frequently asked questions

Does DRV8843PWP require external MOSFETs?

No. The DRV8843PWP integrates Power MOSFETs in four half-bridges. It is a fully integrated driver — control logic and power stage in one package. No external H-bridge or FETs are needed.

What is the maximum output current of DRV8843PWP?

Each half-bridge is rated for 1.75 A continuous output current. This is the per-channel limit; total package current depends on thermal dissipation through the HTSSOP exposed pad.

How does DRV8843PWP compare to DRV8811PWPR?

Both are fully integrated bipolar stepper/brushed DC drivers with four half-bridges in similar packages. The DRV8811PWPR has a lower 8 V maximum load voltage and slightly higher 1.9 A output current, while the DRV8843PWP handles 45 V load voltage at 1.75 A. Choose DRV8843PWP for higher-voltage rails (up to 45 V) and DRV8811PWPR for higher-current (1.9 A) designs at 8 V.
