Product details
Overview
P9382A-0AHGI8 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/demodulation, and operates in -40°C to +85°C ambient.
For engineers reviewing the P9382A-0AHGI8 datasheet, P9382A-0AHGI8 pinout, P9382A-0AHGI8 application, or P9382A-0AHGI8 equivalent, key selection factors include its TRx dual-mode capability, 53-DSBGA package footprint, I²C 400kHz interface, MTP firmware programmability, and integrated overvoltage/overtemperature protection for mobile and IoT wireless charging designs.
Technical Context
The P9382A-0AHGI8 implements a fully programmable WPC 1.2.4–compliant wireless power stack using an embedded 32-bit ARM® Cortex®-M0 core, enabling real-time load modulation for Rx-to-Tx communication and dynamic power negotiation. Its on-chip full/half-bridge inverter drives external L-C tanks in Tx mode, while its synchronous full-bridge rectifier and LDOs (1.8V/5.0V) regulate output in Rx mode.
It integrates dedicated DEMOD circuitry for backchannel signal detection, PCLAMP for reliable overvoltage clamping, and GPIOs for fault indication and system control - all within a single die optimized for EMI performance and thermal efficiency in compact portable devices.

No, the P9382A-0AHGI8 integrates a 32-bit ARM® Cortex®-M0 processor that executes the complete WPC protocol stack, modulation/demodulation logic, safety monitoring, and GPIO control - eliminating the need for an external MCU in most TRx implementations. The P9382A-0AHGI8 supports standalone operation with only host-level configuration via I²C. External MCUs are optional for advanced system-level coordination but not required for core wireless power functionality.
What is the maximum operating temperature range for the P9382A-0AHGI8?
The P9382A-0AHGI8 is rated for continuous operation from -40°C to +85°C ambient temperature. Its on-die thermal sensor and ARM® Cortex®-M0–managed thermal throttling ensure safe operation under sustained 20W Rx or 6W Tx loads. The 53-DSBGA package's thermal resistance (θJA) is 62°C/W, validated per JEDEC JESD51-2A. Derating curves in the official datasheet define power limits above 70°C ambient.
Can the P9382A-0AHGI8 be used in both transmitter-only and receiver-only configurations?
Yes, the P9382A-0AHGI8 supports three operational modes: transmitter-only, receiver-only, and full TRx - configured via firmware and pin strapping. In Tx-only mode, it drives external L-C tanks up to 6W; in Rx-only mode, it delivers up to 20W with synchronous rectification. The P9382A-0AHGI8's MTP memory stores mode-specific calibration data and safety thresholds, enabling reliable reconfiguration without hardware changes.
What package type and mounting requirements apply to the P9382A-0AHGI8?
The P9382A-0AHGI8 uses a 53-ball DSBGA package measuring 2.80 × 4.00 mm with 0.4 mm ball pitch and 0.6 mm height.
