P9243-GB Datasheet | Renesas

Description The P9243-GB is a highly integrated, magnetic induction, wireless power transmitter that supports up to 15W in pliance with the WPC-1.2.4 specification or proprietary applications. It is patible with all popular wireless charging protocols including the WPC Baseline Power Profile (BPP), Extended Power Profile (EPP), up to 7.5W charging for i Phones, and Samsung Fast Charge. This system-on-chip solution (So C) operates with an input voltage range of 5V to 19V. The P9243-GB transmitter IC includes an industry-leading 32-bit ARM® Cortex®-M0 processor, offering a high level of programmability and extremely low standby power consumption. The P9243-GB has only pre-programmed bootloader firmware in the internal memory, and must be used in conjunction with an external flash memory that contains application firmware. This architecture gives the user the flexibility to change the firmware in the external flash to meet application-specific requirements. The P9243-GB transmitter generates power through the power coil, detects the presence of a wireless power receiver, decodes the munication packets from the receiver, and adjusts the transmitted power by controlling the voltage based on feedback from the receiver. The device is specially designed to support fixedfrequency operation as described in the WPC MP-A11 coil configuration with an external input step-down buck regulator. It uses an external oscillator for very accurate 127.7k Hz fixed frequency operation. The transmitter detects if a foreign metal object is placed on the transmitter pad via advanced Q detection. The microcontroller empowers the user to customize foreign object detection (FOD) threshold settings. The I2C serial munication allows the user to read the transmitter’s basic information, such as voltage, current, frequency, and fault conditions. The P9243-GB is available in a lead-free, space-saving 48-VFQFPN package. The product is rated for a -40ºC to +85ºC operating temperature range. Typical...
