ML7660-311HB
13.56MHz無線充電電源接收器 (for REF66003, 300mW, WL-CSP)
ML7660是13.56MHz無線電源接收LSI。ML7660可與ML7661結合使用，建構一個最大輸出功率為1W的無線電力傳輸系統。ML7660是一個13.56MHz無線電力傳輸LSI。ML7660採用2.28mm x 2.61mm (2.44mm平方等效) WLCSP晶片或5mm平方32引腳WQFN封裝，提供用於測量電源狀態和無線電源控制功能的10位元ADC，使其成為小型設備無線電源供應的理想LSI。此外，它具有主機介面（SPI (周邊)/I²C (目標)）功能，以及串列介面（SPI (控制器)/I²C (控制器)/UART）功能，可從外部微控制器更新設定資料和控制各種感測器。
