Description
The P9415 is a highly-integrated single-chip wireless power
transmitter/receiver IC (TRx). The device 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 micro controller to
produce an AC power signal to drive external L-C tank. As a
receiver, the device 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 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 features Multiple-time programmable (MTP) nonvolatile memory to easily update control firmware and device
functions.
The device 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 high
level of programmability while consuming extremely low standby
power. The processor can also control GPIOs to indicate operating
and fault modes. The P9415 is available in an ultra-small
53-WLCSP package.
