Description
The IC has precision output current and voltage-sensing scheme over the entire load range. It enables accurate received power packets, as defined in the WPC specifications for best foreign object detection (FOD). The IC supports FSK demodulation to receive PMA advertisement ID as well as WPC FSK packets.
The IC features the patent-pending PeerPower™ function. In PeerPower mode, the IC operates as a transmitter, enabling power transfer to another peer device through in-band ASK communications.
The MAX77950 communicates with an application processor through an I2C serial interface. The status of power transfer and alerts are read through this interface.
