Features Single Chip Receiver (Rx) Solution WPC v1.1.2 Compliant PMA v1, v3 Pre-Release Compatible with Options Advanced WPC v1.1.2 Foreign Object Detection (FOD) Programmable FOD setting via external resistor and I2C registers Programmable current limit via external resistor Integrated Full-Bridge Synchronous Rectifier Integrated 5V @ 1A LDO Regulator Output Closed-loop power transfer control between TX and RX I2C interface provides VRECT, Iout and switching frequency values Open-Drain LED Indicator Output Over-Temperature/Voltage/Current Protection Applications WPC-Compliant and PMA-Compatible Wireless Chargers for Mobile Applications. Cellular Mobile Phones Tablets, DSC, DVC and Handhelds Introduction The P9028AC is an integrated single-chip, dual-mode WPC v1.1.2-compliant and PMA v1.0-compatible, wireless power receiver IC with advanced WPC v1.1.2 Foreign Object Detection (FOD). The device operates with an AC power signal from a resonant tank and converts it into a regulated 5V output voltage, which can be used to supply power to a mobile application. It includes a high efficiency Synchronous Full Bridge Rectifier and 5V tracking LDO output stage. The P9028AC dual-mode operation automatically detects the transmitter type and initiates either WPC or PMA AC modulation communication protocols with optimal efficiency. The device includes the control circuit required to modulate the load to transmit WPC-compliant or PMA-compatible message packets to the base station. It uses minimal external components to reduce overall solution area. The P9028AC employs advanced programmable WPC FOD techniques to detect foreign metallic objects placed on the transmitter base station derived from a transmitted and received power transfer algorithm. The P9028AC is available in a 36 ball 3mm X 3mm WLCSP or 32 pin 5mm X 5mm TQFN package. Typical Application Circuit Packages: WLCSP-36 6x6 balls (3.06mm x 2.9mm) (See page 33) TQFN-32 5x5mm (See page 35) Ordering information: (See page 38) |
