DRV2625: question about the initialization procedure - Datasheet error?

Part Number: DRV2625

We are using the DRV2625 haptic driver and have a question about the initialization procedure. On page 63 of the datasheet, step 3 in the initialization procedure states “Write the MODE parameter (address 0x01) to value 0x00 to remove the device from standby mode.”

I find this statement very confusing since address is 0x01 is a read-only status register (see page 36) and the MODE parameter is in address 0x07 (see page 39).

Can you provide some clarification of this statement?

    Hey Jay,

    This one is weird, you are right. The MODE parameter is a different address as you stated and, on top of that, writing anything into it won't remove device from a standby mode, it still needs a trigger for that.

    I will check this one with my colleague and try it out if necessary, but for now I would consider this statement very questionable. He will be back on Tuesday and we ll try to give you an answer as soon as possible!

    Best regards,
    Marko

    Hi Jay,

    This is a typo in the datasheet. Please ignore this step. The device has an automatic go-to-standby state. The device will come out of standby to play a waveform and then enter standby at the end of the waveform. There is no control for putting the device into standby mode.
