Description
The P9247-V 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-V includes an industry-leading 32-bit ARM®
Cortex®-M0 processor, offering a high level of programmability
and extremely low standby power consumption.
The P9247-V 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 Features support for Ventiva® Ionic Cooling
Engine (ICE™). P9247-V application firmware integrates drivers
for the cooling engine. ICE operation is based upon the principle
of ionization which creates airflow without any moving parts and
without any noise. This allows for high power transmitter design
without needing a fan.
The P9247-V is available in a lead-free, space-saving
48-VFQFPN package. The product is rated for a -40ºC to +85ºC
operating temperature range.
