DRV8812: Returning time from Sleep mode

Part Number: DRV8812

Hi,

Could you let me know the maximum returning time from Sleep mode, please?
Datasheet of page 12 shows that Typ value is 1ms.
We want to know max time.

Best regards,
Shimizu

    Hi Shimizu-san,

    I would consider the value of 1 ms on page 12 to be the maximum time needed to come out of sleep mode. Technically, this value is not an official datasheet specification because we do not test for it during characterization or production testing. The time needed for the device to come out of sleep mode to being fully operational depends on a variety of factors we cannot characterize. In particular, the charge pump is shut off in sleep mode, and it needs time to become operational. This is largely dependent on the external capacitors and layout, so it is difficult for us to fully characterize the time needed to come out of sleep mode.
