P9038 8W, Qi-Compliant Wireless Power Transmitter
● IDT’S TRANSMITTER SOLUTION enables the development of USB-powered wireless charging bases with 75% fewer ICs than competing solutions. The P9038 is a highly-integrated, WPC 1.1.2-compliant wireless power transmitter targeted for A5 and A11-type coils.
● It is designed to support both USB and AC adapter input voltages ranging from 4.5 to 6.9 V and is capable of supporting receivers with up to 8W of power, exceeding the power transfer requirement specified by the WPC standard.
● The transmitter includes integrated full-bridge inverter, current sense, and Foreign Object Detection (FOD) circuitry to minimize overall printed circuit board real estate and Bill of Material (BOM) cost. The 19mΩ R_DS(ON) typical values for the full-bridge inverter output FETs make them ideal for high efficiency applications. A proprietary slew rate control design results in ex-tremely low EMI that is well below the CISPR standard, eliminating the need for a separate EMI filter and further reducing the overall BOM cost.
