DRV8301 RESET

Other Parts Discussed in Thread: DRV8301

Hello,

I am using DRV8301 driver for my motor control application. I have trouble with reseting latched driver error. When some of them occure (e.g. GVDD undervoltage) I am not able to reset this error diferent way than power supply cycling.  I have already tried toggling with the EN_GATE signal and reset by the SPI command, but still doesn't work. Has somebody similar experience?

Thanks.

David

    Hi David,

    Our expert has been notified and should reply soon.

    Any additional information you can provide will be helpful, such as scope captures, schematics, voltages.

    Also please note the second paragraph of section 7.3.4.2 on page 19 of the datasheet (SLOS719D, August 2015). Could you be experiencing the transient described in this paragraph?

    Hi David,

    As Rick mentioned, please examine section 7.3.4.2 of the datasheet. Any information you can supply including supply voltage, transient scope captures, and schematic will be helpful.
