Hi!
I'm facing an interesting problem. I am trying to config the charging on my custom design. I have 2x2 Li-Ion cell (2 parallel cells in series), Rchg = 0.016R on high side, Rsns = 0.005R resistor on low side, and the adapter voltage is 12V. I would like to charge with 1.5A max.
When I connect adapter ACLW still set, ACFET is off, and CHGR bit in Charger Status is off too. But! the system current is +463mA, (which is looks correct, because there is 100R load on the output, and the adapter current is 420mA) so it is charging (I confirmed with oscilloscope, the charging fets are switching like heaven), but not with the 1.5A which I set.
I attach the srec file, and a printscreen, any remark can help, thank you in advance!
