DRV8840: DRV8840 is protected while the connection of motor winding is broken
Part Number: DRV8840Dears,I am using DRV8840 to drive an DC motor, the working current is about 1A. And we found that the DRV8840 will enter a protect and need reset to re-enable, it seems to be OCP....

Hi Rick, EN_GATE is set to logic high during power up. But, I dont understand 'clear the fault' advice. How can I do that? Doing that in GUI spi register tab? Savas
View ArticleRE: BOOSTXL-DRV8305EVM: SPI register show that VCPH_UVFL pin is fault
Hi Savas,Please write to the CLR_FLTS bit in the IC Operation Register. This should clear the fault. If the fault does not return it could have been set during the power up procedure.
