Bipolar stepper driver with integrated power stage
The BD6385EFV-E2: The ROHM BD6385EFV- is a fully integrated bipolar stepper motor driver that combines the control logic and DMOS power stage in a single 40-HTSSOP-B package.
Step resolution and interface
The parallel interface accepts step and direction commands directly from a host MCU without serial protocol overhead. Step resolution is selectable between full-step, half-step, and quarter-step — the 1/4 microstep mode reduces low-speed torque ripple and audible noise in applications like desktop printers or medical pumps. Four half-bridge outputs drive the two bipolar stepper windings.
