9.6 Common testing and debugging issues
Table 18. Common issues and causes
Indication of the issue
Possible causes
No VOUT voltage
• VRECT voltage too low
– misalignment of the coils too big
– insufficient transmitter power
• RX protection triggered
LED D7 blinking
• Communication cannot be established
– misalignment
– other communication problems (e. g. noise)
LED D7 off
• Receiver is not powered
– misalignment
– transmitter not powered
– transmitter protection triggered
Power transfer terminated
• Charging complete
• Foreign object detected
• Communication error
Excessive IC temperature
• High LDO power loss
– LDO drop set too high
– Modulation depth too high
