ML7651-F00GD
Power Transmitter LSIs (13.56MHz Wireless Charge : WQFN, battery-charging)

ML7651 is a 13.56MHz wireless power transmitter LSI. ML7651 realizes a wireless power transfer system by combining with the wireless power receiver LSI ML7650, and can output 3W to ML7650. ML7651 has a communication command generation function for communicating with ML7650, 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 ML7650 is attached/detached or power is transmitted. All of these functions are included in the 40-pin WQFN package (6.0 mm square), and ML7651 is ideal for wireless power transfer 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, ML7651 is equipped with a host interface (SPI / I²C slave) function, and it is possible to update configuration data from an external MCU.
