P9036-0NTGI

The Renesas P9036-0NTGI is a highly-integrated, single-chip WPC1.1-compliant wireless power transmitter IC designed for power transmitter applications. It operates from a 12V (±5%) supply and features an integrated half-bridge inverter for efficient DC/AC conversion. The device controls transferred power by modulating its switching frequency between 115kHz and 205kHz at a fixed 50% duty cycle, adhering to WPC specifications for A6 3-coil transmitters.

This IC includes logic circuits to demodulate and decode WPC-compliant message packets from mobile devices, allowing it to adjust transferred power dynamically. It manages all three coils in the WPC TX-A6 configuration, performing detection and charging control autonomously. The P9036-0NTGI also supports optional 2-way communication security and encryption up to 64-bit, along with a proprietary back-channel communication mode for enhanced authentication.

Key features include over-current and over-temperature protection, programmable Foreign Object Detection (FOD), and power good/fault condition detection with LED indicator outputs. It is housed in a compact 48-WFQFN exposed pad package, suitable for surface mounting. Applications include charging mats, public facilities like shops and airports, office furniture, PC docks, portable instruments, and medical devices.

The P9036-0NTGI supports master/slave I2C interface and is designed for applications requiring reliable and secure wireless power transmission.
