Evaluation Board for Motor Driver IC TB67S249FTG

Outline
The TB67S249FTG is a two-phase bipolar stepping motor driver using a PWM chopper. CLK-IN control system and BiCD process are adopted. Rating of 50 V and 4.5 A is realized.
This evaluation board mounts necessary components to evaluate the IC. Each excitation mode of full step, half step, quarter step 1/8 step, 1/16 step, and 1/32 step is possible with PWM constant current drive. Please sense low-noise and low-vibration drive of stepping motors applying the TB67S249FTG.

Note
In using, please be careful about the thermal condition sufficiently.
As for each control signal, please refer to the IC specification by accessing to the below URL.
