Part Number: DRV8912-Q1

Hi，

The MCU SPI interface is connected to DRV8912QPWPRQ1 through SN74LVC244ADBR. The customer wants to cascade 60 motors. May I ask if it is possible to drive or if there is a better solution recommended？

Thanks！

Hello,

The DRV8912-Q1 supports "daisy chain" operation so the SDO pin of the first device can be connected to the SDI of the 2nd device in the chain. This would be my recommendation.

Regards,

Ryan
