1. Describe

IDT P9260 and P9261-3CNLG28 are highly integrated magnetic induction wireless power transmitter controllers that support WPC Qi Normative or proprietary applications. depending on Product code, P9260/61 can use a single coil or Multiple coils in a full-bridge or half-bridge inverter configuration. P9260 is designed to support single coil applications, and P9261 is used for multi-coil design. P9260/61, including industry-leading 32-bit ARM® The Cortex®-M0 processor provides a high level of programmability and Standby power consumption is extremely low. The transmitter generates electricity through the power coil to detect whether there is Wireless power receiver, decoding comes from Receiver, and adjust the transmit power through control Based on the voltage fed back by the receiver. The launcher will Make the power receiver output 15W if bidirectional Can establish communication protocol, or power receiver For a standard 5W power receiver, only 5W will be output. The transmitter detects whether foreign objects are placed on the transmitter Transmitting coil. Protect malfunctioning equipment and systems P9260/61 includes input under voltage, input over voltage, output short circuit and over temperature protection. Microcontrollers enable users to customize functions, such as As LED mode, foreign object detection (FOD) threshold setting, Or over-temperature threshold. The device supports I2C Serial interface protocol that enables users to control basic Parameters, such as operating mode, switching frequency, input Current and input voltage. P9260 adopts lead-free, space saving 7 × 7 mm size, 48-QFN wettable side package. The product was rated The operating temperature range is -40ºC to +105ºC.
