Wireless Power Transmitter forSmartphones with Fast ChargingP9247Modes and 30W ApplicationsShort-Form DatasheetDescriptionFeatures The P9247 is a highly integrated, magnetic induction, wireless Power transfer up to 30W in proprietary mode and 15W at power transmitter that supports up to 15W in compliance with receiver side in EPP mode the WPC-1.2.4 specification and 30W in proprietary applications. Real-time foreign object detection (FOD) The device is compatible with all popular wireless charging protocols including the WPC Baseline Power Profile (BPP), Wide input voltage range: 5V to 19V Extended Power Profile (EPP), up to 7.5W charging for iPhones, Supports various types of wall adapters and Android proprietary fast charging modes. This system-on-chip WPC-1.2.4 compatible solution (SoC) operates with an input voltage range of 5V to 19V Integrated drivers for external power MOSFETs and supports various types of wall adapters. Embedded 32-bit ARM® Cortex®-M0 processor (trademark of The P9247 includes an industry-leading 32-bit ARM® Cortex®-M0 ARM, Ltd.) processor, offering a high level of programmability and extremely Simultaneous voltage and current demodulation scheme for low standby power consumption. WPC communication The P9247 generates power through the power coil, detects the Integrated current sense amplifier presence of a wireless power receiver, decodes the communication Low standby power packets from the receiver, and adjusts the transmitted power by controlling the voltage based on feedback from the receiver. Active-LOW enable pin for electrical on/off Over-current and over-temperature protection The transmitter also features a wide range of system protections, such as over-current, over-voltage, under-voltage lockout, and Supports I2C interface real-time foreign object detection (FOD), ensuring maximum utility -40 to +85°C ambient operating temperature range and safety for customers. The transmitter also allows for power 48-VFQFPN (6 6 mm) RoHS-compliant package adjustment via frequency, duty-cycle, and/or bridge voltage adjustment, and offers significant margin to EMI requirements in all Typical Applications regions of the world. BPP and EPP wireless charging pads The P9247 is available in a lead-free, space-saving 48-VFQFPN package. The product is rated for a -40ºC to +85ºC operating Up to 7.5W charging for iPhones temperature range.
