Beschreibung

The TC7766WBG is a 15W wireless power receiver (RX) ICcompliant to the Qi v1.2 standard of the Wireless PowerConsortium (WPC). The TC7766WBG includes a rectifier circuit,a digital control circuit, a modulation circuit, a demodulationcircuit and a regulator circuit which controls the supply voltage tothe load. The IC includes all functions needed to construct astandalone wireless power RX system. In addition, it enables ahost controller to check the wireless power system status byaccessing its registers via I2C. TC7766WBG allows designes witha minimum amount of external components. e.g. uses an internaloscillator and generates its own power supply voltages with anbuilt-in LDO.
