AS3956 − Electrical Characteristics

All limits are guaranteed. The parameters with min and max

values are guaranteed with production tests or SQC (Statistical

Quality Control) methods.

Operating Conditions

All in this specification defined tolerances for external

components need to be assured over the whole operation

conditions range and also over lifetime.
