Product details
Overview
P9260-BNLG28 from Renesas Electronics (formerly IDT) is an AEC-Q100 Grade 2 qualified automotive wireless power transmitter controller implementing WPC Qi 1.2.4 compliance for single-coil 15W applications. It integrates a 32-bit ARM® Cortex®-M0 processor, supports 9V–16V input, delivers bidirectional FSK/ASK communication, and features integrated half-bridge drivers with wettable-flank 48-QFN packaging.
For engineers reviewing the P9260-BNLG28 datasheet, P9260-BNLG28 pinout, P9260-BNLG28 application, or P9260-BNLG28 equivalent, key selection criteria include its automotive-grade thermal range (−40°C to +105°C), I²C/SPI programmability, foreign object detection (FOD) with Q-factor monitoring, integrated LDOs (3.3V/1.8V), and dedicated remote temperature sensing capability.
Technical Context
The P9260-BNLG28 implements a fixed-frequency, duty-cycle-controlled wireless power topology with embedded PWM generator and FSK modulator for bidirectional communication with Qi receivers. Its ARM Cortex-M0 core executes firmware for real-time power regulation, FOD decision logic, and configurable LED status patterns.
It integrates dual half-bridge gate drivers (BST_BRG1/GL_BRG1/GH_BRG1/SW_BRG1 and BST_BRG2/GL_BRG2/GH_BRG2/SW_BRG2), analog front-end with ISNS_IN/ISNS_H/ISNS_L current sensing inputs, and ADC channels for VDEM1/VDEM2/VDEM3 demodulation and DIETEMP monitoring - all operating within CISPR-25-compliant EMI constraints.

Equivalent & Alternatives
The following parts are listed as comparable options for similar wireless power transmitter controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MP-A20 (NXP Semiconductors) | Single-coil Qi 1.2.2 transmitter; lacks ARM M0 core - uses hardwired state machine; no remote temperature sense pin. | Supports only basic 5W/7.5W; no firmware-upgradable FOD or alignment features. | Lower-cost option for non-automotive consumer docks where AEC-Q100 and 15W are not required. |
| STWLC38 (STMicroelectronics) | Integrated power stage (no external FETs); 5W-only; uses proprietary MCU core; no wettable flank package. | Targeted at space-constrained portable accessories; lacks CISPR-25 compliance and automotive qualification. | Preferred for compact USB-powered chargers; unsuitable for 12V automotive systems or 15W output. |
Compared with MP-A20 and STWLC38, the P9260-BNLG28 uniquely combines AEC-Q100 Grade 2 qualification, 15W Qi 1.2.4 compliance, programmable ARM M0 firmware, and wettable flank packaging - making it the only choice for production automotive in-cabin transmitters requiring long-term reliability and field-upgradability.

FAQ
What is the maximum wireless power output supported by the P9260-BNLG28?
The P9260-BNLG28 supports up to 15W output when communicating with a WPC Qi 1.2.4–compliant receiver and successfully completing bidirectional handshake. With legacy 5W receivers, it defaults to 5W mode. Output is dynamically adjusted based on receiver feedback and subject to thermal and foreign object detection limits enforced by the P9260-BNLG28's embedded firmware.
Does the P9260-BNLG28 require external MOSFETs for power stage implementation?
Yes, the P9260-BNLG28 requires external discrete MOSFETs. It integrates dual half-bridge gate drivers (with BST, GH, GL, SW pins) but does not include power switches. This architecture allows design flexibility in selecting FETs optimized for voltage rating, RDS(on), and thermal performance - a key requirement for automotive 15W systems using the P9260-BNLG28.
Is the P9260-BNLG28 pin-compatible with the P9261 series?
No, the P9260-BNLG28 is not pin-compatible with the P9261. While both share the same 48-QFN footprint, their pin functions differ significantly - especially in bridge driver assignments (P9260 uses single-bridge configuration; P9261 supports dual-bridge/multi-coil) and GPIO mapping. PCB layout must be specific to P9260-BNLG28; migration to P9261 requires redesign.
What interfaces does the P9260-BNLG28 support for host microcontroller communication?
The P9260-BNLG28 supports both I²C (SCL/SDA) and SPI (SCLK/SS/SPI_D0/SPI_D1) interfaces for host MCU communication. I²C is typically used for configuration and status monitoring, while SPI supports higher-speed firmware updates. Both interfaces allow real-time adjustment of parameters including switching frequency, input current limit, FOD thresholds, and LED behavior - all executed by the ARM Cortex-M0 core inside the P9260-BNLG28.
How does the P9260-BNLG28 implement foreign object detection (FOD)?
The P9260-BNLG28 implements multi-parameter FOD using Q-factor measurement, voltage/current phase shift analysis, and power loss monitoring - all processed by its embedded ARM Cortex-M0. It also supports optional external NTC via the DIETEMP pin for coil temperature correlation. This approach meets WPC Qi requirements and avoids false triggers from non-metallic objects, ensuring safe operation in automotive environments where the P9260-BNLG28 is deployed.
