We use i.MX6 for industrial equipment.
The equipment needs RTC.
It has usually stopped for a long time in many cases.
Therefore, in order to keep RTC operation for a long time, it must have a large capacity backup battery.
We use MMPF0100 with i.MX6.
However, the current which can be supplied from MMPF0100 for LICELL charge is 60uA.
Therefore, the charge for the large capacity LICELL cannot be finished within the equipment operation period.
We will change the i.MX6-SDP schematics to which it refers, in order to remove 60uA limitation.
It gets the charging current from GEN_3V3.
Is our schematics available as the file attached here?
Is there any point which takes care?
