5.7.3 Dynamic OVP
Protects the power receiver from abrupt rises of the VRECT voltage. It predicts the rises based on the operational
parameters of the transmitter (ring, bridge voltage, current).
5.7.4 Current Drop OVP
Protects the power receiver from overvoltage caused by drops of load. The detection is based on Tx measured
bridge current drop amplitude.
5.7.5 Ring node overvoltage
Protects the Tx ring node against overvoltage, which may be caused by an atypical Rx coil, unexpected
z‑distance or XY offset. It is triggered by direct ring node voltage measurement and is referred in raw ADC values.
