DRAFT Dual-Mode WPC/PMA 5 Watt Wireless Power Receiver IC P9028AC Product Datasheet Features Introduction Single Chip Receiver (Rx) Solution The P9028AC is an integrated single-chip, dual-mode WPC WPC v1.1.2 Compliant v1.1.2-compliant and PMA v1.0-compatible, wireless power PMA v1, v3 Pre-Release Compatible with Options receiver IC with advanced WPC v1.1.2 Foreign Object Advanced WPC v1.1.2 Foreign Object Detection (FOD) Detection (FOD). The device operates with an AC power Programmable FOD setting via external resistor and signal from a resonant tank and converts it into a regulated 2 I C registers 5V output voltage, which can be used to supply power to a Programmable current limit via external resistor mobile application. It includes a high efficiency Synchronous Integrated Full-Bridge Synchronous Rectifier Full Bridge Rectifier and 5V tracking LDO output stage. The Integrated 5V 1A LDO Regulator Output P9028AC dual-mode operation automatically detects the Closed-loop power transfer control between TX and transmitter type and initiates either WPC or PMA AC RX modulation communication protocols with optimal efficiency. 2 I C interface provides VRECT, Iout and switching The device includes the control circuit required to modulate frequency values the load to transmit WPC-compliant or PMA-compatible Open-Drain LED Indicator Output message packets to the base station. It uses minimal Over-Temperature/Voltage/Current Protection external components to reduce overall solution area. The P9028AC employs advanced programmable WPC FOD Applications techniques to detect foreign metallic objects placed on the WPC-Compliant and PMA-Compatible Wireless transmitter base station derived from a transmitted and Chargers for Mobile Applications. received power transfer algorithm.
