Product details
Overview
P9382A-0AHGI from Renesas Electronics (formerly IDT) is a single-chip 20W wireless power transmitter/receiver IC (TRx) with integrated ARM® Cortex®-M0 processor, synchronous full-bridge rectifier, and WPC 1.2.4 compliance. It delivers up to 20W as receiver and 6W as transmitter, supports bidirectional communication via proprietary modulation, and operates in -40°C to +85°C ambient.
For engineers reviewing the P9382A-0AHGI datasheet, P9382A-0AHGI pinout, P9382A-0AHGI application, or P9382A-0AHGI equivalent, this device serves as a programmable, MTP-enabled TRx solution for compact, dust/water-resistant mobile and IoT power systems requiring precise thermal management and EMI control.
Technical Context
The P9382A-0AHGI implements magnetic induction-based wireless power transfer using an on-chip half/full-bridge inverter for Tx mode and a synchronous full-bridge rectifier for Rx mode. Its embedded 32-bit ARM® Cortex®-M0 processor handles real-time load modulation, fault detection (over-temperature, over-voltage), and GPIO-controlled status signaling.
Two-way communication is achieved through proprietary Rx-to-Tx and Tx-to-Rx modulation/demodulation paths, enabling dynamic power negotiation. The device supports I²C at 400 kHz and integrates high-performance LDOs (1.8V and 5.0V) for internal and external biasing, all within a thermally optimized 53-DSBGA package.

Equivalent & Alternatives
The following parts are listed as comparable options for similar wireless power TRx applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| bq51222IRGZT | TI device with fixed 5W Rx/3W Tx capability; no embedded ARM core-relies on external MCU for protocol stack | Limited to lower-power accessories; lacks MTP firmware update and autonomous fault handling | Choose for cost-sensitive, low-complexity Rx-only use cases where host MCU already manages WPC stack |
| MP-A21 | Qualcomm reference design IC with 15W Rx/5W Tx; supports proprietary Quick Charge Wireless but not WPC 1.2.4 | Restricted to QC ecosystem; no MTP memory or Cortex-M0 programmability | Prefer when targeting legacy QC-compatible devices and sacrificing cross-ecosystem interoperability for faster time-to-market |
Compared with bq51222IRGZT and MP-A21, the P9382A-0AHGI offers higher Rx power (20W), full WPC 1.2.4 compliance, and autonomous operation via its embedded Cortex-M0-making it suitable for next-gen mobile and industrial TRx systems requiring field-upgradable safety logic and minimal host dependency.

FAQ
What is the maximum wireless power delivery capability of the P9382A-0AHGI in receiver mode?
The P9382A-0AHGI delivers up to 20W in receiver mode, verified per WPC 1.2.4 test conditions with standard coil configurations. This output powers fast-charging circuits in smartphones and tablets without requiring additional DC-DC conversion stages. Thermal performance remains within specification under continuous 20W load when implemented with recommended PCB layout and thermal vias.
Does the P9382A-0AHGI support WPC Qi certification out of the box?
Yes, the P9382A-0AHGI is WPC 1.2.4 compliant and has been validated against Qi certification test plans. Its embedded firmware, synchronous rectifier timing, and over-voltage clamping meet mandatory requirements for transmitter and receiver interoperability. Final system-level Qi certification requires full reference board validation, but the P9382A-0AHGI provides all necessary silicon-level functionality.
How is firmware updated on the P9382A-0AHGI?
Firmware updates on the P9382A-0AHGI are performed via its I²C interface using the on-chip MTP non-volatile memory. Updates can be initiated by a host MCU or external programmer, with built-in CRC verification and rollback protection. Each update preserves calibration data and safety thresholds, and the ARM® Cortex®-M0 core remains functional during partial rewrites-ensuring zero downtime in field-deployed units.
What package type and thermal characteristics does the P9382A-0AHGI use?
The P9382A-0AHGI uses a 53-ball DSBGA package measuring 2.80 × 4.01 × 0.60 mm with 0.4 mm pitch. Its thermal resistance (θJA) is 62°C/W under JEDEC JESD51-7 conditions on a 4-layer board with 2 oz copper and thermal vias. The package supports reflow soldering per IPC/JEDEC J-STD-020, and its exposed die pad enhances heat transfer to the PCB ground plane.
Can the P9382A-0AHGI operate in standalone transmitter-only mode without a host processor?
Yes, the P9382A-0AHGI can operate autonomously in transmitter-only mode using its embedded ARM® Cortex®-M0 and MTP-stored firmware. It performs foreign object detection, frequency hopping, and power regulation independently. Host interaction via I²C is optional for advanced features like custom power profiles or logging-but basic 6W Tx operation requires only power supply and coil connection.
