Evaluation Board for Motor Driver IC TB67S109AFTG

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.

In using, please be careful about thermal condition sufficiently.
As for each control signal, please refer to the IC specification by accessing to the below URL.
Further, the application of this evaluation board is limited to the purpose of evaluating and learning the motor control. Please do not ship them to a market.
