ML7661-320GD
13.56MHz 無線充電電源發射器 (1W, WQFN)
ML7661是13.56MHz無線功率傳輸LSI。ML7661可與ML7660結合，組成可向ML7660提供高達1W功率的無線供電系統。ML7661具有與ML7660通訊的通訊命令產生功能、用於優化功率傳輸的可變功率傳輸控制功能，以及在ML7660連接、分離或供電時檢測異物等無線功率傳輸功能，所有這些功能都整合在6mm平方40引腳WQFN封裝中。它是小型設備無線供電的理想LSI。操作電壓設定為5V，允許該設備由行動電源等USB電源供電。此外，它還具有主機介面（SPI（周邊）/I²C（目標））功能和序列介面（SPI（控制器）/I²C（目標））功能。序列介面（SPI（控制器）/I²C（控制器）/UART）功能可從外部微控制器更新配置資料和各種感測器控制。
