WB8118

Application

WB8118 is a highly efficient, Qi-compliant, magnetic inductive wireless power transmitter ic with wide input voltage range of 3.3V to 18V. it supports secure communication with wireless power receiver (ASK).fixed communication interface ports, as well as reliable over-voltage current temperature protection schemes.

It includes voltage regulator, full bridge and drivers.ASK de-modulator, FSK modulator, foreign object detection (FOD), PWM modules, multi-channel 12-bit ADC.

l2C interface is used for communication with other devices.

The WB8118 is available in a Pb-free, QFN 3mm x4mm x 0.55mm,24 pin package. This product is rated over an operating temperature range of .40℃ to 105℃.
