P9415-1AWQI8集成電路（IC）的電源管理-專用規(guī)格書PDF中文資料

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.
