5.9 Rectifier and VRECT Level

Once VRECT powers up to greater than UVLO, the full-bridge rectifier switches to half synchronous or full synchronous mode (depending on

the loading conditions) to efficiently transfer energy from the transmitter to the load applied to VOUT. The VRECT pin must not be directly

loaded. The rectified voltage will automatically self-adjust based on the programmed output setting to regulate throughout for all phases of

charging to maintain adequate headroom that is balanced with optimal efficiency.

5.10 Interrupt Output

In Wireless Power RX mode, the /INT pin can be programmed to go LOW to indicate that an over-current, over-voltage, or over-temperature

event has occurred. This feature is programmable and can be implemented using the /INT.
