Hello,
I need to use Shutdown power saving mode, but I need that when the device turns on again the Remaining Capacity has a valid value.
Q1) I understand this is possible because of the available information in BQ34110 Technical Reference Manual, items 3.2.56, 3.2.57 and Table 3-2. Am I right?
Q2) However, I tried the following:
a) Shut down and turn on the chip
b) During microcontroller operation once every 1 second I send subcommands STORE_REMCAP_A and STORE_REMCAP_B (1ms separation between these two subcommands) to store RC in data flash
c) Same as (b), but sending a Device Reset command after turning on
In all of these cases the RC after turning off and on is different from the actual remaining capacity.
I tried these options based on the available information in BQ34110 Technical Reference Manual, but it seems that this information is unclear or incomplete. Please give some further instructions on how to achieve the RC storing and retrieval from data flash.
Thanks in advance,
Gustavo
