Renesas Unveils Complete Lithium-Ion Battery Management Platform with Pre-Validated Firmware

　　Pre-programmed Firmware to Simplify Development

　　Firmware is essential in battery management systems as it is used to monitor batteries’ state of charge (SoC), state of health (SoH), current, and temperature, as well as actively balancing the voltages of the individual cells, and detect faults. In some cases, however, consumer electronics developers may lack the highly specialized expertise needed to develop control algorithms that keep the batteries operating in a safe temperature region and ensure adequate battery life over many charge/discharge cycles.

　　Renesas’ R-BMS F solutions include built-in, pre-tested firmware designed to work with the FGIC’s on-board MCU. The firmware includes critical pre-programmed functions to maximize battery life and ensure safe operation. These include cell balancing, current control, and voltage and temperature monitoring. For added flexibility, the battery management system lets developers set many parameters to meet specific requirements and adjust the solution for different cell chemistries via a graphical user interface (GUI), without the need for a full integrated development environment (IDE).

　　“One of the biggest bottlenecks for designing advanced power management solutions is the complex task of firmware development and validation,” said Chris Allexandre, Senior Vice President and General Manager of Power at Renesas. “Not everyone has the expertise or in-house resources to write their own algorithms. Our all-in-one R-BMS F battery management system eliminates this process and provides market-ready power solutions that work without requiring specialized technical knowledge of MCU programming or advanced battery management design.”

　　All-Inclusive Evaluation Kits Ready to Ship

　　Both R-BMS F solutions contain a full evaluation kit, which has all the hardware, software, tools and documentation required to start developing. The underlying hardware powering the R-BMS F is Renesas’ FGIC solution, which combines an analog battery front end and an ultra-low-power RL78 MCU into a single, small package. The analog portion provides accurate measurements of cell voltage, current and temperature, as well as controlling the external MOSFETs and converting analog data to digital signals. The digital section is where synchronous functions reside, including the main CPU, clocks, timers and serial interfaces. Also included in the evaluation kits are: pre-programmed firmware stored in embedded flash memory with the flexibility to set the battery pack and cell chemistry parameters; the USB System Management Bus (SMBus) interface; GUI-based software; cables to communicate with the host system; dedicated development tools for parameter setting; and full documentation, including schematics and an engineering bill of materials (eBOM). With these resources, developers can confidently innovate intelligent power management systems that safely monitor battery usage and provide longevity, while reducing their impact on the environment. Renesas plans to include turn-key R-BMS F solutions in all future FGICs.

　　2-4 Cell Series Solution (RTK0EF0163DK0002BU)

　　The R-BMS F for 2 to 4S cell (~8V to 16V) solutions targets small vacuum cleaners, robotic vacuums, consumer and medical devices and runs on Renesas’ RAJ240055 Li-ion battery FGIC. Renesas offers Smart Robot Vacuum Cleaner | Renesas by combining this FGIC with other devices from its portfolio.

Renesas Strengthens Power Leadership with New GaN FETs for High-Density Power Conversion in AI Data Centers, Industrial and Charging Systems

　　Renesas Electronics Corporation (TSE:6723), a premier supplier of advanced semiconductor solutions, introduced three new high-voltage 650V GaN FETs for AI data centers and server power supply systems including the new 800V HVDC architecture, E-mobility charging, UPS battery backup devices, battery energy storage and solar inverters. Designed for multi-kilowatt-class applications, these 4th-generation plus (Gen IV Plus) devices combine high-efficiency GaN technology with a silicon-compatible gate drive input, significantly reducing switching power loss while retaining the operating simplicity of silicon FETs. Offered in TOLT, TO-247 and TOLL package options, the devices give engineers the flexibility to customize their thermal management and board design for specific power architectures.　　The new TP65H030G4PRS, TP65H030G4PWS and TP65H030G4PQS devices leverage the robust SuperGaN® platform, a field-proven depletion mode (d-mode) normally-off architecture pioneered by Transphorm, which was acquired by Renesas in June 2024. Based on low-loss d-mode technology, the devices offer superior efficiency over silicon, silicon carbide (SiC), and other GaN offerings. Moreover, they minimize power loss with lower gate charge, output capacitance, crossover loss, and dynamic resistance impact, with a higher 4V threshold voltage, which is not achievable with today’s enhancement mode (e-mode) GaN devices.　　Built on a die that is 14 percent smaller than the previous Gen IV platform, the new Gen IV Plus products achieve a lower RDS(on) of 30 milliohms (mΩ), reducing on-resistance by 14 percent and delivering a 20 percent improvement in on-resistance output-capacitance-product figure of merit (FOM). The smaller die size reduces system costs and lowers output capacitance, which results in higher efficiency and power density. These advantages make the Gen IV Plus devices ideal for cost-conscious, thermally demanding applications where high performance, efficiency and small footprint are critical. They are fully compatible with existing designs for easy upgrades, while preserving existing engineering investments.　　Available in compact TOLT, TO-247 and TOLL packages, they provide one of the broadest packaging options to accommodate thermal performance and layout optimization for power systems ranging from 1kW to 10kW, and even higher with paralleling. The new surface-mount packages include bottom side (TOLL) and top-side (TOLT) thermal conduction paths for cooler case temperatures, allowing easier device paralleling when higher conduction currents are needed. Further, the commonly used TO-247 package provides customers with higher thermal capability to achieve higher power.　　“The rollout of Gen IV Plus GaN devices marks the first major new product milestone since Renesas’ acquisition of Transphorm last year,” said Primit Parikh, Vice President of the GaN Business Division at Renesas. “Future versions will combine the field-proven SuperGaN technology with our drivers and controllers to deliver complete power solutions. Whether used as standalone FETs or integrated into complete system solution designs with Renesas controllers or drivers, these devices will provide a clear path to designing products with higher power density, reduced footprint and better efficiency at a lower total system cost.”　　Unique d-mode Normally-off Design for Reliability and Easy Integration　　Like previous d-mode GaN products, the new Renesas devices use an integrated low-voltage silicon MOSFET – a unique configuration that achieves seamless normally-off operation while fully capturing the low loss, high efficiency switching benefits of the high- voltage GaN. As they use silicon FETs for the input stage, the SuperGaN FETs are easy to drive with standard off-the-shelf gate drivers rather than specialized drivers that are normally required for e-mode GaN. This compatibility simplifies design and lowers the barrier to GaN adaptation for system developers.　　GaN-based switching devices are quickly growing as key technologies for next-generation power semiconductors, fueled by demand from electric vehicles (EVs), inverters, AI data center servers, renewable energy, and industrial power conversion. Compared to SiC and silicon-based semiconductor switching devices, they provide superior efficiency, higher switching frequency and smaller footprints.　　Renesas is uniquely positioned in the GaN market with its comprehensive solutions, offering both high- and low-power GaN FETs, unlike many providers whose success in the field has been primarily limited to lower power devices. This diverse portfolio enables Renesas to serve a broader range of applications and customer needs. To date, Renesas has shipped over 20 million GaN devices for high- and low-power applications, representing more than 300 billion hours of field usage.
