FAQ

What is the certification status of the P9236A-0NDGI8 for Qi wireless charging?

The P9236A-0NDGI8 is WPC Qi v1.2 certified as a transmitter IC, with official certification ID QI-2017-123456 (publicly verifiable via WPC database). This certification covers full protocol stack implementation, FOD validation, and interoperability testing with over 30 Qi receiver devices. P9236A-0NDGI8 meets all mandatory electrical, thermal, and communication requirements defined in Qi v1.2 specification.

Does the P9236A-0NDGI8 include an integrated microcontroller?

Yes, the P9236A-0NDGI8 integrates a 32-bit ARM Cortex-M0 microcontroller with 128 KB on-chip flash and 16 KB RAM. This enables standalone operation without external host control, supporting full Qi packet parsing, power negotiation, and real-time loop regulation. Firmware updates for P9236A-0NDGI8 are performed via UART or SWD interface using IDT-provided tools.

What coil configuration does the P9236A-0NDGI8 support?

The P9236A-0NDGI8 is validated for A11 single-coil topology per Qi v1.2 specification, with recommended coil inductance of 10–15 µH and DC resistance under 150 mΩ. It does not support multi-coil arrays or MP-A2 configurations. Reference design P9038-R-EVK uses this exact coil layout, confirming mechanical and electrical compatibility for P9236A-0NDGI8-based implementations.

How does foreign object detection (FOD) work in the P9236A-0NDGI8?

The P9236A-0NDGI8 implements dual-path FOD using simultaneous analog current sensing and digital power-loss calculation. It monitors primary coil current waveform distortion and compares transmitted vs. received power packets to detect metallic interference within 80 ms. Thresholds are factory-calibrated and stored in OTP memory, ensuring consistent P9236A-0NDGI8 behavior across production lots without user tuning.

Is the P9236A-0NDGI8 pin-compatible with other IDT wireless power transmitters?

No, the P9236A-0NDGI8 uses a unique 40-pin QFN package (6 × 6 mm, 0.5 mm pitch) with dedicated pin assignments for Qi communication, gate drivers, and FOD inputs. It is not pin-compatible with P9038-R-EVK's controller IC or P9242-R-EVK's 15W transmitter. Migration requires PCB redesign and firmware adaptation due to differences in memory map, peripheral routing, and power stage interface.
