Overview

WPC/PMA Dual Mode Wireless Power Receiver
Compliant with WPC Low Power (v1.2) and PMA SR1 (v2.0)
Peer-to-Peer Power Transmission with In-Band ASK Communications
WPC ASK Demodulator/FSK Demodulator
Output Programmable Range from 3.5V to 12.7V with 100mV Step
Integrated High-Efficiency n-Channel Full-Bridge Synchronous Rectifier
Programmable Foreign Object Detection
Programmable Dynamic Rectifier-Voltage Scaling
Overvoltage, Overcurrent, and Overtemperature Protection

The MAX77950 is an advanced wireless power receiver IC that meets the specification requirements for WPC low-power (v1.2) and PMA SR1 (v2.0) communication protocols. This device operates using near-field magnetic induction when coupled with a WPC or PMA transmitter and provides output power up to 12 watts.

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.
