Description

The P9415-R is a highly integrated single-chip wireless power

transmitter/receiver IC (TRx) that can be configured to receive or

transmit an AC power signal through magnetic induction.

When the device is configured as a wireless power transmitter, it

uses an on-chip full/half-bridge inverter, a PWM generator, a

modulator/demodulator for communication, and a microcontroller

to produce an AC power signal to drive external L-C tank. As a

receiver, the P9415-R receives an AC power signal from a wireless

transmitter and converts it into rectified output voltage, which can

be used to power devices or supply the charger input in mobile

applications. The P9415-R integrates a high-efficiency

Synchronous Full Bridge Rectifier and control circuitry to modulate

the load to send message packets to the Transmitter (Tx) to

optimize power delivery.

The P9415-R features Multiple-time programmable (MTP) nonvolatile memory that enables customers to customize the design

parameters such as default output voltage and FOD thresholds.

The P9415-R includes over-temperature and voltage protection.

Fault conditions associated with power transfer are managed by an

industry-leading 32-bit ARM® Cortex®-M0 processor offering a high

level of programmability while consuming extremely low standby

power. The processor can also control GPIOs to indicate operating

and fault modes. The device is available in an ultra-small

53-WLCSP package.
