P9028A-0NBGI

Overview

The P9028A-0NBGI is an integrated single-chip wireless power receiver IC designed for dual-mode operation, compliant with WPC v1.1 standards and compatible with PMA protocols. It converts AC power signals from a resonant tank into a regulated 5V output voltage suitable for mobile applications. The device features an advanced Foreign Object Detection (FOD) system, a high-efficiency synchronous full-bridge rectifier, and a 5V tracking LDO regulator. It supports automatic dual-mode switching between WPC AC and PMA DC modulation connections to optimize efficiency.

Feature Summary

• Dual-mode support for WPC v1.1 compliance and PMA compatibility
• Integrated full-bridge synchronous rectifier and 5V tracking LDO
• Advanced programmable foreign object detection via external resistor or I2C
• Closed-loop power transfer control with I2C interface for monitoring

Applications

• Wireless charging base stations for mobile devices
• Automatic dual-mode wireless power receivers
• Consumer electronics requiring WPC v1.1 and PMA support

Procurement Notes
