Wireless Power Transmitter with
Ventiva® ICE™ Support for Fast
Charge Applications
P9247-V
Short-Form Datasheet
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.
Features
Power transfer up to 30W in proprietary mode and 15W at
receiver side in EPP mode
Ionic Cooling Engine (ICE™) support which allows for airflow
without any moving parts and noise
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
ARM, Ltd.)
Simultaneous voltage and current demodulation scheme for
WPC communication
Integrated current sense amplifier
Low standby power
Active-LOW enable pin for electrical on/off
Over-current and over-temperature protection
