Product details
Overview
P9021-0AHGI8 from Renesas Electronics is a dual-mode wireless power receiver IC compliant with both WPC 1.0.1 (Qi) and PMA Type 1 standards, integrating synchronous full-bridge rectifier and synchronous buck converter to deliver regulated 5 V output at up to 5 W in WPC mode, used in smartphones and Bluetooth accessories for contactless charging.
For engineers reviewing the P9021-0AHGI8 datasheet, P9021-0AHGI8 pinout, P9021-0AHGI8 application, or P9021-0AHGI8 equivalent, key selection considerations include dual-standard interoperability, integrated FOD with thermal loop control, I²C programmability, 64-bit SHA encryption support, and WLCSP package compatibility with compact mobile PCB layouts.
Technical Context
The P9021-0AHGI8 implements closed-loop power transfer control via load modulation for bidirectional communication with base stations, supporting both WPC-compliant packet messaging and optional proprietary back-channel communication. It embeds an MCU for fault management, LED status indication, and GPIO configuration.
Its power architecture combines AC-to-DC conversion through a synchronous full-bridge rectifier followed by regulation via a synchronous buck converter with BUCK5VR_IN input and BUCK5VR_SNS feedback. Protection includes over-temperature, over-voltage, over-current, and multi-layer foreign object detection (FOD) with user-programmable thresholds.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-mode wireless power receiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| bq51222IRGZT | TI part supports WPC 1.2.2 only; no PMA compatibility; uses external MOSFETs for rectification and buck stages. | Lacks dual-standard operation; requires additional gate drivers, FETs, and layout area - unsuitable for space-constrained PMA-inclusive designs. | Select only if WPC-only operation suffices and board area allows discrete power stage implementation. |
| MP-A21 | Integrated PMA-only receiver; no WPC support; smaller 3.5 mm × 3.5 mm WLCSP but lacks I²C and GPIO flexibility. | Targeted at PMA-specific accessories; missing SHA encryption, multi-layer FOD, and programmable status outputs. | Choose when cost-sensitive PMA-only deployment is acceptable and security/FOD requirements are minimal. |
Compared with bq51222IRGZT and MP-A21, the P9021-0AHGI8 uniquely delivers certified dual-standard operation with fully integrated power stages, I²C configurability, and robust safety features - making it the only option for compact, globally compliant, and secure mobile receiver designs.

FAQ
Does the P9021-0AHGI8 support both WPC and PMA standards simultaneously?
Yes, the P9021-0AHGI8 natively supports both WPC 1.0.1 and PMA Type 1 standards within a single silicon die and firmware image. It automatically detects and negotiates with compatible transmitters without external mode selection circuitry. The P9021-0AHGI8 achieves this through integrated protocol stacks and shared power conversion hardware, enabling true dual-mode interoperability in production devices.
What is the function of the PGOOD pin on the P9021-0AHGI8?
PGOOD is an open-drain status output that asserts high when the REC_OUT rail is within regulation (5 V ±2%) and all internal protections are inactive. It interfaces directly with system PMICs or host MCUs for power sequencing and fault reporting. In the P9021-0AHGI8, PGOOD deasserts within 10 µs of overvoltage, overtemperature, or FOD events, providing deterministic system-level response.
Can the P9021-0AHGI8 operate without an external microcontroller?
Yes, the P9021-0AHGI8 contains an embedded MCU that autonomously handles protocol negotiation, power control, FOD, and fault recovery. While I²C allows host configuration, basic wireless charging operates stand-alone using factory-default settings. The P9021-0AHGI8 does not require continuous host intervention to maintain compliant power transfer.
What package type and dimensions does the P9021-0AHGI8 use?
The P9021-0AHGI8 uses a 48-ball Wafer-Level Chip-Scale Package (WLCSP) measuring 4.65 mm × 4.86 mm with 0.4 mm ball pitch. This ultra-compact footprint supports placement beneath displays or batteries in smartphones and wearables. The package is RoHS-compliant and qualified per J-STD-020 moisture sensitivity level 3.
How does foreign object detection (FOD) work in the P9021-0AHGI8?
The P9021-0AHGI8 implements optional multi-layer FOD combining real-time Q-factor monitoring, temperature gradient analysis, and power deviation tracking. It compares expected vs. measured coil behavior during power transfer and triggers shutdown within 100 ms if anomalies exceed programmable thresholds. This method satisfies WPC and PMA certification requirements without external thermistors or auxiliary sensors.
