verter from 110kHz to 205kHz. All the logic and
other circuitry needed to receive and decode
WPC compliant packets from the mobile device
and to execute the requested power adjustments are also fully integrated into the IDTP9030. It contains
logic circuits required to demodulate and decode WPC compliant message packets sent by the mobile
device to adjust transferred power.
IDTP9030 also may be operated in proprietary modes where it employs additional proprietary functions
such as two extra levels of Foreign Object Detection (FOD), 2-way secure authentication between base
and mobile, and IDT proprietary control algorithms for higher efficiency.
SAFETY FEATURES
