Outline
】
The TB67S109A is a two-phase bipolar stepping motor driver using a PWM chopper.
CLK-IN control system and BiCD process are adopted. Rating of 50V and 4.0A is
realized.
This evaluation board mounts necessary components to evaluate the IC. Each
excitation drive of full step, half step, quarter step 1/8 step, 1/16 step, and 1/32 step
can be run with PWM constant current drive. Please sense low noise and low
vibration of the stepping motor.
