13.56MHz 無線充電電源發射器 (適用於無電池控制，WQFN)
ML7661-210GD
13.56MHz 無線充電電源發射器 (適用於無電池控制，WQFN)
Description
ML7661是13.56MHz無線電力傳輸LSI。ML7661可與ML7660結合，建立一個能為ML7660供應高達1W電力的無線電源系統。ML7661具備與ML7660通訊的通訊指令產生功能、最佳化電力傳輸的可變電力傳輸控制功能，以及在ML7660連接、分離或供電時偵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針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，允許設備透過USB電源（如行動電源）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。
