I have been using the bq24600 for several years in designs with 4s LiPos and 5A with no problems. Now I am trying to use it with a 6s LiPo and a charge current of 5A. If I configure it for 3A it works fine, but as soon as I change the value to 5A it shuts down with no current. I have tried changing the inductor from 3.3 uH to 2.2uH as the datasheet for the EVM suggests for higher current with no change in behavior.
I am using it on a board design that has been very successful at lower voltage and current. I have plenty of heat sinking; the MOSFETs run at 45 deg C at 3A. I am using different MOSFETs than I have used in the past but they are TI 60V, 118A NexFETs (CSD18533KCS).
Any ideas would be welcome.
