MAX77950EWW+

WPC/PMA dual mode wireless power receiver operates using near field magnetic induction when coupled with a WPC or PMA (SR1 (v2.0)) transmitter. It 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 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. Typical applications include smartphones, tablets, smart watches, headsets, wearable devices, battery power banks, Wi-Fi hotspots, digital cameras, portable media players, point-of-sale and handheld devices.

• 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 dynamic rectifier voltage scaling
• Overvoltage, overcurrent and overtemperature protection
• I2C interface
