The P9260 is a highly integrated, magnetic induction wireless power transmitter controller supporting the WPC Qi specifications or proprietary applications. The P9260 functions with a single coil in a full-bridge or half bridge inverter configuration.

The P9260, which includes an industry-leading 32-bit ARM® Cortex®-M0 processor, offers a high level of programmability and extremely low standby power consumption. The transmitter generates power through the power coil, detects the presence of a wireless power receiver, decodes the communication packets from the receiver, and adjusts the transmitted power by controlling the voltage based on feedback from the receiver. The transmitter will enable the power receiver to output 15W if the bidirectional communication protocol can be established, or the power receiver will output only 5W for a standard 5W power receiver.

The transmitter detects if a foreign metal object is placed on the transmitter coil. To safeguard the device and the system under fault conditions, the P9260 includes input under-voltage, input overvoltage, output short-circuit, and over-temperature protection.

The microcontroller empowers the user to customize features such as LED patterns, foreign object detection (FOD) threshold settings, or the over-temperature threshold. The device supports the I2C serial interface protocol, which enables the user to control the basic parameters, such as operating mode, switching frequency, input current, and input voltage.

The P9260 is available in a lead-free, space-saving 7 × 7 mm, 48-QFN wettable flank RoHS-compliant package. The product is rated over the operating temperature range of -40ºC to +105ºC.
