Hi Team,

If default state of DRV8303 is OK for an application, can this device work without SPI control?

Thanks and regards,

Hi Mahendra

Yes. It is possible if all functions and protections works for you.

Best regards,

Hello Wilson,

Also, if this device needs to be used to drive single phase motor, do you see any challenge?
Basically, customer plan to use only two half-bridges to drive a single phase motor.

If yes, can INH_C, INL_C, BST_C, GH_C, SH_C, GL_C, SL_C be left floating? or you recommend an alternate method?

Hi Mahendra,

This method should be OK. We also have the DRV8701 if they just need an H-bridge driver.

Hi Nick,

Thanks for confirming!
DRV8701 was discussed with customer but it's available only in VQFN package which is not suitable for their production line.

Understood. Was there a specific issue in the production line (pick and place, reflow, ICT, visual inspection)?

Do you know what kind of opportunity size this is? Placing the DRV8701 in a leaded package is always something we can look at in the future. Feel free to contact me over the E2E messaging system.
