Product specification
Product Overview
The Beilande D9812 is a single-chip, three‑port wireless charging transmitter controller that integrates all the control functions required for Qi 2.2 wireless charging, supporting 5W, 7.5W, 10W, and 15W EPP/MPP as well as 25W MPP charging. The chip incorporates a Type‑C controller, compatible with fast‑charging protocols such as PD 3.0 (PPS) and QC 3.0, and employs a highly integrated dual‑chip architecture to simultaneously manage wireless charging for smartphones, smartwatches, and earbuds. The system features multi‑channel, fully synchronous digital demodulation, supports cycle‑by‑cycle hardware OCP protection, and implements foreign object detection (FOD) by continuously monitoring power‑transfer efficiency. The device is packaged in a 6mm × 6mm, 48‑pin QFN package.
