ML7660-311HB
13.56MHz Wireless Charging Power Receiver (for REF66003, 300mW, WL-CSP)
ML7660 is a 13.56MHz wireless power receiving LSI. ML7660 can be combined with ML7661 to create a wireless power transfer system with a maximum power output of 1 W. ML7660 is a 13.56 MHz wireless power transfer LSI. ML7660 provides a 10-bit ADC for measuring power supply status and wireless power supply control functions in a 2.28 mm x 2.61 mm (2.44 mm square equivalent) WLCSP chip or 5 mm square 32-pin WQFN package, making it the ideal LSI for wireless power supply in small devices. In addition, it has a host interface (SPI (peripheral) / I²C (target)) function and a serial interface (SPI (controller) / I²C (target)) function, The serial interface (SPI (controller) / I²C (controller) / UART) function enables configuration data update and various sensor controls from an external microcontroller.
