I have a bq28z610EVM board and I've been stepping through the setup procedure in the evaluation guidance document. The document says that the firmware is defaulted to a two cell configuration so I have been using a voltage divider on the input side hooked up to a bench top power supply set to 7.4 volts across pins 1N and 2P. The board has been tested with no load, with a 10kohm load, and with a charger applied. I have also used a single 18650 cell (4.2 volts) between 1N and 1P with 1P and 2P shorted together. In every case, regardless of any permutation that I've tried, the output voltage is not being sustained which indicates that the FETs (CHG and DSG) are not turning on. These have been probed independently with a multi-meter to confirm. VC1 and VC2 voltages have also been verified. Is there a shutdown condition that I might be overlooking that would cause the IC to turn off immediately after turning on so that it looks like it is not turning on? Any advice appreciated. Thanks for your time.
