P9035A-0NTGI

Overview

The P9035A-0NTGI is a highly integrated wireless power transmitter IC compliant with Wireless Power Consortium (WPC) version 1.1 specifications for power transmitter designs A5 and A11. It operates from a 5V input supply, supporting a range of 4.75V to 5.25V. The device utilizes an external full-bridge inverter to provide efficient power transfer. It controls transferred power by modulating the switching frequency between 110kHz and 205kHz at a fixed 50% duty cycle. The IC demodulates and decodes WPC-compliant message packets from mobile devices to adjust power levels.

Feature Summary

• Complies with WPC version 1.1 standards for A5 and A11 transmitter designs
• Integrates logic circuits for demodulating and decoding mobile device messages
• Features proprietary back-channel communication via I2C interface
• Includes over-temperature and over-current protection mechanisms

Applications

• Wireless power base station design A5
• Wireless power base station design A11
• 5V wireless charging transmitter systems

Procurement Notes
