Other Parts Discussed in Thread: TPS65381-Q1

My customer is using TPS65381-Q1.
I have a question about the not cleared resister at RESET mode.

In RESET mode, Is the register which isn't cleared only DEV_ERR_CNT register?
Or are there any other?

Thanks,
Shimizu

Hi Shimizu-san,

During RESET all TPS65381 registers remain the same. If the RESET is a Power On RESET (POR), involving the supply to the device, then all registers will be reset.

Hi Scott-san

Thank you for your support.
Is this also same by STANDBY mode?

Thanks

It applies to all states. Only a POR (power on reset) where the supply of the device goes below the VBAT undervoltage thresholds will the registers be reset.

Hi Shimizu-san,

I need to correct this response. I overlooked that Standby state if executed normally forces a POR so yes, going through standby will also reset the registers. Sorry for the confusion.
