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.
