Page 1

The P9418 is a highly-integrated single-chip

wireless power transmitter/receiver IC (TRx). The

device configures to transmit or receive an AC

power signal through magnetic induction.

As a wireless power transmitter, the P9418 features

an on-chip full/half-bridge inverter, a pulse-width

modulation (PWM) generator, a

modulator/demodulator for communication, and a

microcontroller to produce an AC power signal to

drive an ex ter n al L-C tank. As a receiver, the device

receives an AC power signal from a wireless

transmitter and converts it to a rectified output

voltage, which can power devices or supply the

charger input in mobile applications. For optimized

power delivery, the P9418 integrates a high-

efficiency Synchronous Full Bridge Rectifier and

control circuitry that modulates the load to send

message packets to the Transmitter (Tx).

The P9418 features multiple-time programmable

(MTP) non-volatile memory to easily update control

firmware and device functions.

Also, the de vice includes over-temperature and

voltage protection. Fault conditions associated with

power transfer are managed by an industry-leading

32-bit ARM

Cortex

-M0 processor that offers a

high level of programmability while consuming

extremely low standby power. The processor also

controls GPIOs to indicate operating and fault

modes.

The P9418 is avai lab le in an ultr a-small 70-WLCSP

package.
