Hello,
I have a design that is utilising a BQ2050h gas gauge IC to report battery capacity. The battery is a 12V lead acid and is charged using a UC3906 IC.
I am at a stage where I am attempting to program the expected battery capacity using pull-up/down resistor on the SEGx lines. The values reported when reading the PPU/PPD registers, though appear fixed at 0x81 and 0x80 respectively with no changes when the resistors are changed from SEGx lines. I am using 100K as suggested in the application circuits. I presume these registers only update on initialisation and hence am power cycling the BQ2050h on changes to the resistors.
Look forward to your replies.
