Hi Rick,
Thanks for the reply. I have tested two motors on the DRV8307EVM; one is a 4-pole rotor/6-pole stator with halls spaced at 60deg and the other is a 14-pole rotor/12-pole stator with halls spaced at 120 deg. It's the 14-pole motor that doesn…
Hi,
What you are describing sounds like a hall element. Operation of hall elements are described in section 9.1.1. As the voltage on the output pins separate, the comparator in the DRV8307 detects this as a logic high or logic low and acts accordingly…

I am working on a motor controller design based on the DRV8307, and have the following questions:
1. The DRV8307 datasheet does not specify a parameter for dead-time during FET drive transitions. is this…
Other Parts Discussed in Thread: DRV8307 , DRV8307EVM , DRV8308 Team,
Here're some questions from emails on the DRV8307. I'm translating since the original messages were in Chinese. I've also copied Distributor James Su from Yosun, and TSR Aaron Chen in…
Lukasz, sorry to hear it isn't working. There clearly appears to be a problem with the phase or Hall wiring, or the Hall polarity. For the trial-and-error approach, the DRV8307EVM has 2 jumpers that make it easy to try each Hall polarity. Or if you…
