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.
