P9261-3C-CRBv2 Q-Factor Tuning and Open FOD Thresholds Programming Guide
The P9261 Customer Reference Board 2.0 (CRB) Automotive Grade Wireless Power transmitter is designed to follow the Wireless Power Consortium (WPC) Extended Power Profile (EPP) and Baseline Power Profile (BPP) protocols depending on the type of WPC Rx that is placed onto the charging pad. The Open Foreign Object Detection (FOD) threshold and Q-Factor (Q) measurement is already tuned for the CRB per WPC V1.3 specifications. If needed, however, there are options to fine tune the Open FOD threshold and Q measurement. As per the EPP specification, the P9261 must measure for the presence of Foreign Objects (FOs) before starting power transfer. This measurement is taken during the Q measurement test as part of the P9261 PING phase.
