Hi, by mistake the not needed TS pin was left open in a design (no 5k resistor to ground). Although TS function is disabled in CHARGERCTRL0 Register the charge current is very low (0.25 %). It is actually not charging. STAT2 Register has bits 6, 5 and 0 set to 1b1. All FLAG registers are 0x00. ILIM is set to 300mA and ICHG to 21.59 mA.
Device is running from (externally charged) battery which is a 80mAh 3.7V LiPo. So it can't be drawing too much mA. Adapter is providing 500mA.
Could it be that because TS is open the charging current is limited no matter if TS function is disabled or not?
Thanks.
