I don't understand. Did you tie HIN and LIN together? |

| Seekonk:
I see no reason why you would use two pins on three phase. |
| james_s:
Keep in mind that LIN is inverted and HIN is not, so if you tie both together and drive with the same signal then the output will toggle between the two MOSFETs, which is what you want to happen. |
