Wireless Power Transmitter for
Smartphones with Fast Charging
Modes and 30W Applications P9247
Short-Form Datasheet Description Features The P9247 is a highly integrated, magnetic induction, wireless
power transmitter that supports up to 15W in compliance with
the WPC-1.2.4 specification and 30W in proprietary applications.
The device is compatible with all popular wireless charging
protocols including the WPC Baseline Power Profile (BPP),
Extended Power Profile (EPP), up to 7.5W charging for iPhones,
and Android proprietary fast charging modes. This system-on-chip
solution (SoC) operates with an input voltage range of 5V to 19V
and supports various types of wall adapters.  Power transfer up to 30W in proprietary mode and 15W at ARM® receiver side in EPP mode
 Real-time foreign object detection (FOD)
 Wide input voltage range: 5V to 19V
 Supports various types of wall adapters
 WPC-1.2.4 compatible
 Integrated drivers for external power MOSFETs
 Embedded 32-bit ARM® Cortex®-M0 processor (trademark of Cortex®-M0 The P9247 includes an industry-leading 32-bit
processor, offering a high level of programmability and extremely
low standby power consumption.  The P9247 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.  …
