P9242-G5NDGI8

Power Management - Specialized Overview

The P9242-G5NDGI8 is a fixed-frequency wireless charging power transmitter designed for 15W applications. It operates within an input voltage range of 5V to 19V and complies with the WPC-1.2 specification, including MP-A5 and MP-A11 standards. The device integrates a 32-bit ARM Cortex-M0 processor, drivers for external power FETs, and an internal step-down switching regulator. It supports simultaneous voltage and current demodulation and features a programmable LED pattern. The component is housed in a 6x6 mm 48-VFQFPN package and functions across an ambient temperature range of -40°C to +85°C.

• Includes industry proprietary fast charge modes compatible with iPhone and Android protocols.
• Features integrated drivers for external power FETs and an on-chip step-down switching regulator.

Power Management - Specialized Applications

• Wireless charging transmitters for smartphones supporting up to 15W power transfer.
• Applications requiring compliance with WPC-1.2 Baseline and Extended Power Profiles.
• Systems utilizing WPC MP-A11 coil configurations with fixed frequency operation.

Power Management - Specialized Procurement Notes

Verify component status as obsolete or end-of-life through official Renesas channels before design finalization. Confirm availability of replacement parts such as the P9243-GB series. Ensure all ordering suffixes match specific package and tape-and-reel requirements. Check for recent Product Change Notices regarding assembly site updates or label modifications. Validate that external components meet the specified operating conditions for the integrated regulators.

Power Management - Specialized Selection Notes

Select this part for designs requiring fixed-frequency operation at 127.7kHz compliant with WPC MP-A11 standards. Choose this model when external flash memory is available for firmware customization. Consider this IC for systems needing integrated drivers for external FETs and a built-in buck regulator. Ensure the application supports the 5V to 19V input voltage range and requires compatibility with proprietary fast charging modes.

Power Management - Specialized Part Context

The P9242-G5NDGI8 belongs to the P9242 family of wireless power transmitters from Renesas Electronics. This family includes variants like the P9242-R and P9242-G, which share core functionalities but differ in specific configuration options and compliance levels. The P9242-G series specifically targets fixed-frequency applications, distinguishing it from resonant counterparts. These devices are System-on-Chip solutions integrating processing, control, and power management functions.

Power Management - Specialized Replacement Considerations

The P9243-GB is listed as a direct replacement product for the P9242-G series. Verify pin-to-pin compatibility and firmware migration requirements when transitioning to the P9243-GB. Confirm that the replacement supports the required 15W power transfer and WPC-1.2 compliance specifications.
