Wireless Power Transmitter
ASIC
The NCP6992A is a Wireless Power Transmitter ASIC that provides
power, measurement and supporting functions required for
AIRFUELt-MR-compliant Power Transmitting Unit (PTU). Using
an I2C series link, the NCP6992A interfaces a control processor with a
boost converter, a power amplifier, its matching circuit and power
transmitting resonator. Coupled to the Bluetooth® Low Energy (BLE)

signaling protocol embedded in the control processor, the NCP6992A
adjusts and optimizes the power applied to the transmitter coil by
managing power transfer including efficiency as well as monitoring
fault conditions. The NCP6992 has been designed for scalable power
covering Class 2 (10 W) up to Class 5 (50 W) types of transmitters.
The NCV6992A is the automotive release of this Wireless Power
