Overview

Description

The P9382A is a highly integrated single-chip wireless medium 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, PWM generator, modulator/demodulator for communication, and a microcontroller to produce an AC power signal to drive the 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 P9382A 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 P9382A features multiple-time programmable (MTP) non-volatile 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 a high level of programmability while consuming extremely low standby power to meet global energy-saving requirements. The processor can also control GPIOs to indicate operating and fault modes. The P9382A is available in an ultra-small 53-DSBGA package.
