The EVALAg301 evaluation board is powered through the power receiver coil L1 when placed on the interface surface of the EVALAg311 or another Qi compatible power transmitter. When the Ag301 establishes a wireless power transfer contract to the power transmitter, D1 is illuminated and the output is switched on.
The output 5V is available on J1 pin 1 and 2 or the center pin of J2. 0V will be available on J1 pin 3 and 4 or the outer ring of J2. If J4 is shorted the EVALAg301 will switch off the output and indicate to the power transmitter that the power transfer has completed successfully (e.g. battery fully charged).
If J3 is shorted the EVALAg301 will switch off the output and indicate a wireless power transfer error to the power transmitter (e.g. using an external over temperature circuit).
