New Products • ICs & Semiconductors used in a fault-tolerant system and includes a backup power supply for timer circuits and for retaining data in a stand-by SRAM. When it is not monitoring batteries, the TMPM358FDTFG can enter a low-power stand-by mode, leading to lower power for the total system. The Toshiba Li-ion battery monitoring chipset, TB9141FG and TMPM358FDTFG, begins sampling in first quarter 2013. Volume production is expected by April 2014. Toshiba Launches Li-Ion Battery Monitor Chipset for Automotive Applications Toshiba America Electronic Component, Inc. has announced its Li-ion battery monitor chipset for automotive applications. The chipset includes the industry’s first battery monitor IC capable of checking up to 16 cells per one IC, which simplifies design and lowers costs by reducing the number of components required in an automotive battery monitoring system. The Toshiba chipset is well suited for hybrid electric vehicles (HEV) and electric vehicles (EV), which require enhanced battery technology. “With increasing interest and adoption of electric cars, there is a growing need for chipsets that can improve the performance of the battery operation of these vehicles,” said Deepak Mithani, director analog and imaging business unit, System LSI Group. “Our battery monitor chipset helps improve driving range and battery life and reduces battery costs, significant challenges for electric vehicles. We intend to aggressively expand into the battery monitor chipset business and continue providing solutions that support the unique requirements of hybrid and electric automobiles.” Toshiba’s Li-ion battery monitor chipset is comprised of the TB9141FG 16-channel battery monitor IC and the TMPM358FDTFG automotive safety microcontroller. The chipset detects remaining battery levels, equalizes charging among the cells in a battery pack (cell balancing) and can also detect abnormal battery conditions. The TB9141FG uses a 96 V mixed-signal process that allows it to monitor up to 16 cells at the same time. It also incorporates cell balancing switches for each cell and is able to measure battery voltage while cell balancing. The TB9141FG is able to communicate in a noisy environment, using differential signaling in a daisy chain communication link between two or more TB9141FGs, an important feature for automotive applications. The TMPM358FDTFG is a 32-bit RISC microcontroller built around an ARM Cortex-M3 core and is compliant with functional safety standards such as IEC61508/ISO26262. Toshiba will provide a software library developed under an ISO26262 certified software development process to help make it easier for customers to build a safer and more reliable battery monitoring system. The TMPM358FDTFG is designed to be Battery Power • January/February 2013 TI Transforms Mobile Charging Experience with Wireless Power Making wireless power a reality, Texas Instruments, Inc. (TI) has introduced its first single-chip wireless power receiver with integrated battery charger and a new “free-position” transmitter integrated circuit, which expands the charge area by 400 percent. The two bqTESLA circuits give smartphone users a simpler, stress-free charging experience and help designers implement wireless power technology in more places, such as automotive consoles, charging pads and office furniture. TI’s bq51050B is the industry’s first Wireless Power Consortium (WPC) 1.1 Qi-compliant wireless power receiver with integrated direct battery charger, and enables faster, more efficient charging of smartphones, wireless keyboards and other portable electronics. The 20-V receiver combines rectification, voltage conditioning, communication control and Li-Ion charging capability in a single, tiny integrated circuit, eliminating the need for a separate battery charger circuit. The inductor-free, single-stage design delivers high system efficiency and saves up to 60-percent board space compared to a multi-stage implementation. In addition to the receiver, TI’s bq500410A is the first WPC 1.1-ready wireless power transfer controller to support A6 transmitters. The controller allows a Qi-compliant smartphone or other portable device to charge in a surface area of at least 70 mm by 20 mm, 400-percent larger compared to today’s 18-mm by 18-mm “bull’s-eye” charge space. The bq500410A achieves greater than 70 percent efficiency, and relies on a parasitic metal and foreign object detection feature to safely protect the system and stop delivering power if a metal object is detected between the transmitter and receiver. Wireless power is an emerging technology that creates a better charging experience for consumers, just as Wi-Fi replaced the need to use an Ethernet cable for Internet connectivity. TI’s 28
