TPS65982: OCP point setting for TPS65982 and 983B

Part Number: TPS65982

Hi all,

 My customer need to set OCP point at 4.3A for PPEXT 20V 3.25A PDO but has issue on FW V1.12.0 or  V1.12.8. They get 5.3A OCP result by setting 130% and 150% of peak current, and 3.3A in 100%.

1. Can they use 982 base FW on 983B? Is the OC calculation function the same in 982 and 983B?

2. If I set 130% or 150% peak current on PPEXT PDO. I can get 1.3X or 1.3X OCP currenton that PDO right? Is that the same on 983A/983B/982? Or I have to check ILIMHVEXT value on datasheet to find that value?

Best regards,

Gary
