Hello,
Do we have any information on the maximum drift of the of the offset voltage?
Thanks,

Hi Oscar,
You can probably use the spec from DRV8328 (similar to DRV8329 except DRV8328 doesn't have integrated CSAs)

Hi Yara,
I have a few additional question:
I read on the DS that the LDO is disabled when the DRV is on sleep. So how can the uC control the sleep pin if when the uC is powered through the internal LDO?
Waht is the turn on time after sleep to be fully operating?
From the graph below it seem the LDO is able to provide full power across the full temperature range, correct?
Is the temperature in the graph the ambient or the juntion temperature?
Thanks,
Oscar
Hi Oscar,
The MCU can not be powered by AVDD and be responsible for pulling nSLEEP high. Please refer to the following FAQ that explains in detail:
[FAQ] Considerations when powering MCU from AVDD (DRV8328/DRV8329/DRV8329-Q1)
Waht is the turn on time after sleep to be fully operating?

Is the temperature in the graph the ambient or the juntion temperature?
I believe it is junction temp.
