The Texas Instruments DRV8881ERHRT is a fully integrated motor driver that combines control logic and a power stage in a single package with exposed pad for thermal management.
It is ROHS3 compliant.
Each half-bridge output is rated for 1.4A continuous. For bipolar stepper operation, that is 1.4A per winding; for brushed DC, two bridges can be paralleled per motor.
The driver operates from 6.5V to 45V on both the motor supply and the logic supply — a single rail covers both.
The parallel interface accepts standard logic levels; the 6.5V minimum supply means the logic inputs are referenced to the same rail, so 3.3V logic requires a level shifter if the MCU operates at 3.3V and the driver supply is above 5V. Confirm the input logic thresholds in the datasheet for your specific supply voltage.
