EVALUATION KIT AVAILABLE  
MAX77950  
WPC/PMA Dual Mode Wireless Power Receiver  
General Description  
Benefits and Features  
● WPC/PMA Dual Mode Wireless Power Receiver  
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.  
● 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  
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.  
● 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  
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.  
● Programmable Dynamic Rectifier-Voltage Scaling  
● Overvoltage, Overcurrent, and Overtemperature  
Protection  
The MAX77950 communicates with an application pro-  
cessor through an I²C serial interface. The status of power  
transfer and alerts are read through this interface.  
Ordering Information appears at end of data sheet.  
Applications  
● Smartphones  
● Tablets  
● Smart Watches  
● Headsets  
● Wearable Devices  
● Battery-Power Banks  
● Wi-Fi Hotspots  
● Digital Cameras  
● Portable Medical Applications  
● Portable Media Players  
● Point-of-Sale Devices  
● Handheld Devices
