5.4.1 Configuration file
The prepared configuration can be saved to a file in the PC, or the existing file can be loaded to the GUI.
The mentioned operations can be performed by these two buttons. The standard windows dialog for operations
with files will then appear.

The generated file can also be used later in mass production.
5.4.2 Device parameters
Table 13. List of configurable parameters
Parameter Meaning and notes
FORCE_HIGH_POWER
1 = HIGH_POWER_MODE – prevents the chip from going to low power mode between
analog pings (device not in power transfer).
DeadTime
Dead time between High and Low side of main bridge PWM.
Units based on PWM clock step 1/680 ns ~ 1.47059 ns
0 = set automatically by AFE.
(1)
PotentialPowerW
Potential power of the platform in Watts. Transmitted to RX in Power transmitter
capabilities packet (0x31), byte 1
PowerProfileType
Enables EPP support.
0 = BPP only, EPP Rx will be powered at a reduced rate
2 = BPP + EPP, EPP Rx will be powered in full rate
QfBlock_BlankingTime
Impacts maximum detectable frequency by Qf block.
(1)
QfBlock_TimeOut
Impacts minimum detectable frequency by Qf block.
(1)
PresDet_ApPulseForcedFreq
Frequency used for start of Analog ping before resonance frequency seek is active. In
ticks of the 40 Mhz clock.
(1)
PresDet_ApPulseQfIset
Starting current for analog ping pulse. In units of 0.25 mA. 0 = 0.25 mA.
(1)
PresDet_Thr Threshold for determining whether object appeared on/was removed from the TX coil.
Qfactor_Qtarget
Q factor target value. In 0.1 unit of Q format. The expected value measured by Q module
on empty Tx coil.
Qfactor_Cvalue Main Ctank capacity value in nF.
Qfactor_Radjust
Q factor R adjustment value.
(1)
Qfactor_QfPulseStdIset
Current for Qfactor measurement. In units of 0.25 mA , a zero sets the value to 0.25 mA.
(1)
Qfactor_TempCompens
Allows to deduce resistance discrepancy (in 0.01 mΩ/°C) from the temperature delta. To
keep the same Q through temperature.
(1)
Fod_ThrCoeff FOD threshold coefficient. Use FOD simulator of GUI to deduce its value.
Fod_ThrOffset FOD threshold offset. Use a FOD simulator of GUI to deduce its value.
Fod_LossCorrection1 - 6 FOD input values losses correction. Use a FOD simulator of GUI to deduce its value.
