P9247
Short-Form Datasheet
Description
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.
The P9247 includes an industry-leading 32-bit ARM® Cortex®-M0
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.
The transmitter also features a wide range of system protections,
such as over-current, over-voltage, under-voltage lockout, and
real-time foreign object detection (FOD), ensuring maximum utility
and safety for customers. The transmitter also allows for power
adjustment via frequency, duty-cycle, and/or bridge voltage
adjustment, and offers significant margin to EMI requirements in all
regions of the world.
The P9247 is available in a lead-free, space-saving 48-VFQFPN
package. The product is rated for a -40ºC to +85ºC operating
temperature range.

Special Notes: P9247 48-VFQFPN Package Assembly
Unopened dry packaged parts have a one-year shelf life.
The HIC indicator card for newly-opened dry packaged parts should be checked. If there is any moisture content, the parts must be baked for
a minimum of 8 hours at 125˚C within 24 hours prior to the assembly reflow process.
