Wireless Power Transmitter for Smartphones with Fast Charging P9247 Modes and 30W Applications Short-Form Datasheet Description Features
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
