FAQ
What wireless power standard does the P9236A-0NDGI support?
The P9236A-0NDGI supports the WPC Qi v1.2 Baseline Power Profile (BPP) standard exclusively. It is WPC-certified for interoperability with Qi-compliant receivers and implements full digital demodulation, packet encoding/decoding, and communication handshaking per Qi specification. The P9236A-0NDGI does not support Extended Power Profile (EPP) or proprietary protocols.
Does the P9236A-0NDGI require an external microcontroller?
No, the P9236A-0NDGI integrates an ARM Cortex-M0 processor with on-chip flash and RAM, enabling standalone operation. Firmware for Qi communication, FOD, and power regulation runs internally, eliminating the need for an external host MCU in most 5 W transmitter designs. The P9236A-0NDGI can optionally interface with a host via I²C for advanced configuration.
What coil topology is compatible with the P9236A-0NDGI?
The P9236A-0NDGI is optimized for the WPC A11 single-coil topology, supporting inductance values from 15 µH to 33 µH with quality factor ≥40. It is not compatible with MP-A2 or multi-coil arrays. The P9236A-0NDGI's adaptive frequency control automatically tracks resonant peak shifts caused by coil aging or temperature drift.
How is foreign object detection (FOD) implemented in the P9236A-0NDGI?
The P9236A-0NDGI implements hardware-accelerated dual-parameter FOD using real-time measurement of voltage-current phase shift and amplitude deviation in the resonant tank. This dedicated circuitry meets WPC Class 0 requirements without software intervention. The P9236A-0NDGI reports FOD events via I²C status register and triggers automatic power shutdown within <10 ms.
What package type and thermal characteristics does the P9236A-0NDGI have?
The P9236A-0NDGI is housed in a 5 mm × 5 mm QFN-40 package with exposed thermal pad, rated for operation from −40°C to +105°C ambient. Its thermal resistance θJA is 32°C/W under JEDEC JESD51-7 conditions. The P9236A-0NDGI includes internal thermal foldback that reduces output power above 125°C junction temperature to ensure long-term reliability.
