Product details
Overview
P9415-0AWQI8 from IDT (now Renesas) is a single-chip WPC 1.2.4–compliant wireless power transmitter/receiver IC supporting bidirectional TRx operation. It delivers up to 30W as a receiver and up to 5W as a transmitter, integrates a 32-bit ARM® Cortex®-M0 processor, 24kB MTP memory, synchronous full-bridge rectifier, and dual LDOs (1.8V/5V), and is used in mobile device wireless charging systems with WattShare™ capability.
For engineers reviewing the P9415-0AWQI8 datasheet, P9415-0AWQI8 pinout, P9415-0AWQI8 application, or P9415-0AWQI8 equivalent, key selection criteria include WPC 1.2.4 compliance, TRx mode support, VRECT input range (3.5–23.5V), 53-ball WLCSP package constraints, and I²C 400kHz interface integration for system-level power negotiation and telemetry.
Technical Context
The P9415-0AWQI8 implements a fully integrated magnetic induction TRx architecture with on-chip half/full-bridge inverter for Tx mode and synchronous full-bridge rectifier for Rx mode. Its ARM Cortex-M0 core executes real-time power control algorithms, FOD detection, and bidirectional ASK modulation/demodulation at 2kbps over the power link.
It supports proprietary and WPC-compliant communication protocols, uses internal 12-bit ADC for coil current/voltage sensing, and features hardware-based OVP (24.7V default), thermal shutdown (140°C), and programmable clamping via PCLAMP/ECLAMP_DRV pins - all managed without external microcontroller intervention.

FAQ
What is the maximum wireless power delivery capability of the P9415-0AWQI8 in receiver mode?
The P9415-0AWQI8 delivers up to 30W in receiver mode per its datasheet specifications. This rating assumes proper thermal management using the recommended 10-ball ground connection scheme and operation within the VRECT input range of 3.5V to 23.5V. The device achieves this output through its integrated synchronous full-bridge rectifier and programmable VOUT LDO, making it suitable for flagship smartphone fast-charging applications. Real-world performance depends on coil coupling, alignment, and transmitter compliance.
Does the P9415-0AWQI8 support both WPC-compliant and proprietary wireless power protocols?
Yes, the P9415-0AWQI8 supports WPC 1.2.4–compliant operation in both receiver and transmitter modes, including full packet structure, FOD, and negotiation sequences. It also supports proprietary magnetic induction protocols via its configurable ARM Cortex-M0 firmware engine and hardware ASK modulator/demodulator. This dual-mode capability allows designers to implement custom power profiles or regional variants without changing hardware. The P9415-0AWQI8's MTP memory stores protocol-specific firmware images.
How does the P9415-0AWQI8 handle overvoltage protection during wireless power transfer?
The P9415-0AWQI8 implements three-tiered overvoltage protection: a primary 24.7V rising threshold on VRECT with 1.5V hysteresis, a pre-clamp threshold at 23.4V via the PCLAMP pin, and optional external linear clamping controlled by the ECLAMP_DRV output. When OVP triggers, the device asserts fault interrupts and disables rectifier switching while maintaining LDO bias. These protections are hardware-enforced and operate independently of the ARM Cortex-M0 firmware, ensuring fail-safe behavior even during code execution errors. The P9415-0AWQI8 datasheet specifies absolute maximum VRECT as 26.5V.
Can the P9415-0AWQI8 operate as a transmitter without an external microcontroller?
Yes, the P9415-0AWQI8 can operate autonomously as a transmitter using its embedded 32-bit ARM® Cortex®-M0 processor and on-chip firmware. It generates PWM signals, manages LC tank drive, handles backchannel communication via DEMOD, and executes WPC negotiation - all without host MCU intervention. The I²C interface (OD0/OD1) remains available for optional configuration or telemetry, but is not required for basic 5W Tx operation. The P9415-0AWQI8's 24kB MTP memory stores the complete Tx stack.
What is the function of the nEN pin on the P9415-0AWQI8, and how does it affect system behavior?
The nEN pin on the P9415-0AWQI8 is an active-low enable input that controls operational mode: when pulled high, the device enters diode-mode rectification without ASK modulation (fallback for non-WPC transmitters); when pulled low, full TRx functionality activates, including synchronous rectification, firmware-controlled power negotiation, and bidirectional communication. This pin allows hardware-selectable compatibility modes and simplifies system bring-up. Its VIH threshold is 1.6V and VIL is 0.25V, compatible with standard 1.8V GPIOs. The P9415-0AWQI8 datasheet specifies leakage current below 2.5μA at 5V.
