Renesas Electronics Corporation Power Management - Specialized P9036-0NTGI8

The P9036-0NTGI8 is a single-chip wireless power transmitter IC designed for A6-type coils, compliant with WPC Specification version 1.1. It operates from a 12V (±5%) supply and integrates a half-bridge DC-AC inverter for efficient power conversion. This device manages all three coils in the A6 configuration autonomously, without requiring user supervision, and features dynamic switching capabilities across multiple protocols. The transmitter modulates its switching frequency between 115kHz and 205kHz at a fixed 50% duty cycle, ensuring optimal power transfer. It includes logic circuits for demodulating and decoding communication packets from WPC-compliant receivers, enabling closed-loop power transfer control. Safety features include over-current and over-temperature protection, as well as programmable Foreign Object Detection (FOD). The compact 6mm x 6mm TQFN package makes it suitable for various applications, including charging mats, public facilities, office furniture, and medical devices. The device also supports optional back-channel communication for enhanced security and authentication, making it a versatile choice for wireless power applications.
