Communication and control
The 32-bit core MCU is the supervisor of the whole device and manages all the functional blocks to establish and
maintain communication with the receiver.
Ensure adherence to Qi standard specifications (wherever required), optimize the efficiency by properly adjusting
the operating point and guarantee reliability by monitoring and protecting the device.
3.3
ASK demodulation
Using ASK modulation, the receiver sent Control Error Packets (CEP) to tune operating point for matching load
requirements, the transmitter coil signals are filtered using demodulation filter circuit as shown below and feed in
to VS pin of STWLC68JRF.
