ML7660-311HB
Power Receiver LSIs(13.56MHz Wireless Charge : WL-CSP, REF66003)
ML7660 is a 13.56MHz wireless power receiver LSI. ML7660 realizes a wireless power transfer system by combining with the wireless power transmitter LSI ML7661, and can output 1W to a charging device. ML7660 is equipped with a 10-bit SA-ADC for measuring the power charging status and a wireless power charging control function in a 2.28 mm x 2.61 mm (equivalent to 2.44 mm square) WL-CSP chip or a 5 mm square 32-pin WQFN package. This LSI is ideal for wireless power transfer of small devices. Furthermore, ML7660 is equipped with a host interface (SPI / I²C slave) function, and it is possible to update configuration data from an external MCU.
