ML7661 13.56MHz wireless charging Rx LSI
■ML7661 is a 13.56MHz wireless power transmission device. ML7661 realizes a wireless power supply system by combining with the power receiving device ML7660, and can output 1W for power transmission.
■The ML7661 has a communication command generation function for communicating with the power receiving device ML7660, an external transistor control function for supplying 1W, a function for variably controlling the transmission amount to optimize the transmission power, and a function to detect abnormalities when the ML7660 is attached/detached or power is transmitted. All of these functions are included in the 40-pin WQFN package (6.0mm square), and the ML7661 is the best LSI for wireless power supply of small devices. In addition, the operating voltage is 5V, and it can be driven from a USB power source such as a mobile battery. Furthermore, ML7661is equipped with a host interface (SPI / I2C slave) function and a serial interface (SPI / I2C master, UART) function, and it is possible to update configuration data from an external MCU and control various sensors.
