Another requirement of the WPC v1.0 specification is to send the measured rectifier power. This entitles the Rx
to determine the rectifier voltage and output current in order to report this to the Tx as a percentage of the
maximum output power. This is also handled in the active power transfer loop.
If the device is a bq51014, a special state called the “TERM STATE” is enabled in the active power transfer loop.
This state is used to determine the level of the output current versus the programmed level of termination current
(set by the K TERM factor and R TERM resistor). The primary purpose of this feature is to determine if the charge
status is 100% based on the output current from the Rx. In a condition where the mobile device battery is fully
charged, a low system current (output current from Rx) signature can be determined. This current level
(signature) is set by the end system designer and is termed I TERM-HI . In addition to this current level, there is a no-
load termination current level termed I TERM-LO which is fixed at 40 mA. For the high termination condition to be
