  • DRV8823-Q1 SSTB - is it a strobe/latch or "Active low resets serial interface and disables outputs"

    Other Parts Discussed in Thread: DRV8823-Q1 , DRV8823EVM , SN74LVC1G34 My design consists of several DRV8823-Q1 chips driven by QSPI over more than one command event. There could be 16 (or more) chips which all get an update command, but I'd like them to…

  • Can the DRV8823-Q1 supply 3.3v?

    Resolved
    I noticed that the V3P3 pin is an output and requires a ceramic capacitor to regulate the voltage for the internal logic. I wanted to skip the need for potentiometers for the *VREF inputs and tie them to 3.3v, and saw V3P3 and thought, would that do? …

  • RE: DRV8823 Braking capability and SSTB question

    Resolved
    Hi Karim Q1. Yes. DRV8823 does not support a brake control in its own logic. Even the decay bit is set to "0", disable the channel will give coast operation. Q2. Yes. In datasheet P10 you can find the statement. Best regards,
