DA9062 undocumented status register (0x1A8)

Dear forum members,

I found out that there's an undocumented PMIC status register (address 0x1A8) in the DA9062 - same as in DA9063, where it's documented. ;-)

I know the various status values of this register from DA9063 documentation, but is there more information available about the meaning of each of these five bits?
My PMICs show either 15 (0x0F) or 31 (0x1F) right after power up, and I would like to interpret this condition... (other status conditions in my application match with documentation).

Documented values (from DA9063 datasheet):

Decimal Code
03=RESET(Shutdown)
28= SYSTEM
25=POWER
23=POWER-DOWN
20=POWER1
17=ACTIVE

Thanks in advance!

Hello,

Hello,

Thanks for your input.  PSM_STATE settings are partially intended for device internal use only.

The relevant power modes of the DA9061/2 device are described in the developer’s guide AN-PM-060 which you can find here:

https://www.dialog-semiconductor.com/sites/default/files/an-pm-060_da906...

 

PSM_STATE = 0x15: means wait for SYS_EN – which is a transitory state and if device is stuck in this mode, it could point to an incorrect startup procedure based on configuration. In case you ‘re using an unprogrammed part , please make sure using the DA9062 GUI in power commander mode and  load an ini file before powering up the device.

PSM_STATE = 0x31 is an invalid condition ( bit 5 reserved) – please check again by using same condition on a DA9061/2 evaluation board which is recommended  for editing ini files and developing power sequence which will provide valid PSM_STATE.

regards,

Uli
