Product details
Overview
P9036-0NTGI from IDT is a single-chip WPC 1.1-compliant wireless power transmitter IC for A6-type 3-coil transmitters, operating from 12 V ±5%, integrating a half-bridge inverter, supporting 115–205 kHz frequency modulation at 50% duty cycle, and implementing closed-loop power control via WPC message packet demodulation and decoding for use in charging mats and public facility pads.
For engineers reviewing the P9036-0NTGI datasheet, P9036-0NTGI pinout, P9036-0NTGI application, or P9036-0NTGI equivalent, key selection considerations include WPC 1.1 compliance, integrated 3-coil management, 12 V input operation, programmable foreign object detection, and I²C master/slave interface support for system-level power negotiation and status reporting.
Technical Context
The P9036-0NTGI implements a fixed-duty-cycle (50%) variable-frequency half-bridge inverter to meet WPC TX-A6 spectral and efficiency requirements, with real-time demodulation of back-channel communication packets from compliant receivers to adjust output power. It executes full A6 coil detection, alignment validation, and autonomous charging initiation without host intervention.
Its proprietary back-channel mode enables optional 64-bit encrypted bidirectional communication with IDT receivers (e.g., IDTP9020), supplementing standard WPC device identification and closed-loop control. Safety logic includes hardware-based over-current and over-temperature protection plus programmable FOD thresholds with LED fault indication.

Equivalent & Alternatives
The following parts are listed as comparable options for similar wireless power transmitter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MP-A20 (NXP Semiconductors) | WPC 1.2.3-compliant; supports 15 W; requires external half-bridge drivers; larger 7×7 mm QFN-48 | Targets higher-power applications (e.g., laptop charging); lacks integrated inverter and autonomous 3-coil sequencing | Select MP-A20 only when >5 W output or WPC 1.2.3 compliance is mandatory; expect added layout complexity and BOM cost. |
| STWLC38 (STMicroelectronics) | WPC 1.2.2-compliant; integrates 5 W transmitter + receiver functions; 40-pin QFN; no native A6 coil support | Designed for single-coil TX/RX combo systems; not suitable for A6 3-coil transmitter-only deployments | Choose STWLC38 only for bidirectional or space-constrained single-coil designs-not for P9036-0NTGI's A6-specific role. |
Compared with MP-A20 and STWLC38, the P9036-0NTGI uniquely delivers fully autonomous WPC 1.1 A6 3-coil operation with integrated inverter, making it the only option requiring zero external power switches or host-driven coil arbitration for public charging infrastructure.

FAQ
What is the primary compliance standard supported by the P9036-0NTGI?
The P9036-0NTGI is fully compliant with the Wireless Power Consortium (WPC) Specification version 1.1 for Transmitter Type A6. It implements all mandatory packet structures, timing windows, and closed-loop control protocols defined in that revision-including device identification, power control, and error reporting sequences-without requiring firmware updates to meet baseline certification requirements.
Does the P9036-0NTGI require an external microcontroller to operate?
The P9036-0NTGI can operate autonomously for basic A6 3-coil charging without a host microcontroller, performing coil detection, alignment validation, power negotiation, and FOD checks internally. However, an MCU is needed to configure registers, read status via I²C, and drive LED indicators-making the P9036-0NTGI flexible for both standalone and host-managed implementations.
What is the function of the ADINx pins on the P9036-0NTGI?
The four ADINx pins on the P9036-0NTGI are dedicated analog inputs used for real-time monitoring of coil voltage, current, and phase relationships. They feed internal ADCs that compute Q-factor, detect foreign objects, and validate resonance-enabling hardware-accelerated FOD and closed-loop power adjustment without relying on external signal conditioning circuits.
Can the P9036-0NTGI drive more than three coils?
No-the P9036-0NTGI is specifically architected for the WPC TX-A6 configuration and supports exactly three coils via its three integrated half-bridge driver pairs (COIL1–COIL3). It does not support expansion beyond three coils, nor does it provide multiplexing or time-slicing capability across additional external coils; adding more would require external switching and custom control logic.
Is the P9036-0NTGI pin-compatible with other IDT wireless power transmitters?
No-the P9036-0NTGI is not pin-compatible with other IDT transmitters such as the IDTP9020 receiver or IDTP9015 legacy transmitter. Its 48-lead TQFN layout, power pin assignment (VDD12/VDDIO separation), and dedicated COILx/ADINx terminal mapping are unique to the A6 transmitter architecture and verified only for this specific part number.
