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.
