ML7661-311GD
13.56MHz無線充電電源發射器 (適用於REF66003, 300mW, WQFN)
ML7661是13.56MHz無線電力傳輸LSI。ML7661可與ML7660結合使用，以創建無線電源系統，可向ML7660供應高達1W的功率。ML7661具有與ML7660通訊的通訊命令生成功能、用於優化電力傳輸的可變電力傳輸控制功能，以及在ML7660連接、斷開或通電時檢測異物等無線電力傳輸功能，所有這些都整合在一個6mm方形40接腳WQFN封裝中。它是小型設備無線供電的理想LSI。工作電壓設定為5V，允許設備透過USB電源供電，例如行動電源。此外，它還具有主機介面（SPI (周邊) / I²C (目標)）功能和串列介面（SPI (控制器) / I²C (目標)）功能。串列介面（SPI (控制器) / I²C (控制器) / UART）功能可實現配置資料更新和來自外部微控制器的各種感測器控制。
