DRV8305: Daisy chain configuration in DRV8305

Dinesh P Jinjala

Part Number: DRV8305

Hello,

Can I connect three DRV8305 BLDC Driver with same SPI channels through daisy chain configuration? I am using an MSP430G2553 microcontroller. Whatever the answer is but please give me information about it.

Thank you.

Best Regards,

Hi Dinesh,

The SCLK, SDI, and SDO pins can be connected together.
The nSCS pin for each DRV8305 will require a separate pin to communicate to each device.

Please see figure 1 of www.ti.com/.../slyt441.pdf as an example

Thanks. So daisy chain is not possible. I understand it.
