I purchased the BQ25895EVM and the EV2300 to setup my charger. I have been changing the register settings to test my loads and cant seem to get the SYS output to hold at the SYS_MIN as set in REG03. The voltage on SYS is tracking exactly with VBAT. So the battery voltage is 3.3 under load and the SYS output is matching that voltage. Below is the register dump from the TI software which gives you the setting. Any thoughts on why the SYS voltage isn't holding at 3.7V?
