My new hardware design is identical to the EVM and recommended application circuit in the BQ40Z60 data sheet. Specifically, the battery pack output feeds the CHG_FET and DSG_FET and then it's off to VSYS, feeding the load. Unfortunately only CHG_FET is driven ON with the batteries installed. Is this the default condition? It seems more like a fault.
I can talk to the device through the SMB channel and have set NR high (red) and have also programmed the chemistry. FWIW I can turn on the charger FET's manually.
