Part Number:BQ40Z60
Hello,
I have design and manufactured a charging circuit very similar to the BQ40Z60EVM. The only major change has been to the size of the FETs to accommodate higher discharge rates. I am trying to configure the BQ40Z60 power path to my required specifications. I am having trouble setting the maximum discharge threshold for the battery, the maximum input current from the adapter, and the maximum charging current for the battery.
I have attached my .gg.csv of my current settings. As you can see I've increased OCD1 to -22000 mA and OCD2 to -25000. But whenever I discharge more than ~4-5A the charger shuts off the discharge FET until I remove the load. If I have the adapter present I can source up to ~7-8A from the adapter even though I've set OCC1 to 5000mA and OCC2 to 6000mA.
I'm assuming I am missing something and have my settings wrong.
thanks,
Chris
