As part of its new HEV/EV system solution, Intersil today introduced a second device that provides a 12-channel automotive grade Li-Ion battery fault and safety monitor. To address the safety requirements of an HEV/PHEV(plug-in hybrid)/EV Li-Ion battery system, the ISL78601 provides independent and redundant fault monitoring when used in conjunction with the ISL78600 battery management system (also introduced today, see related news release).

Advanced Analogic Technologies, Inc. today introduced its AAT1409/7/5 family of multi-string LED backlight drivers. Offering integrated boost converters and precision current sinks that can support up to 88 LEDs at 360mA total LED current, the AAT1409/7/5 drivers are among the most powerful in the marketplace. These new drivers bring to market a fully featured solution that reduces the number of backlight PCBs, reducing costs, yet is capable of d...

Advanced Analogic Technologies, Inc. (AnalogicTech) introduced the AAT1451, a high-efficiency white LED driver for liquid crystal display (LCD) backlighting applications in portable electronic devices such as the fast-growing tablet and the established computer markets.

By combining a high performance charge pump, with backlight, flash and RGB drivers into a single 4 x 4mm IC controllable by a serial interface, AnalogicTech’s AAT2830/31 reduces parts count and system footprint, offering handset and portable system designers an exceptionally high level of integration and configurability.

Texas Instruments has introduced today a family of battery charger front-end integrated circuits, which dramatically increases protection when charging a cell phone or other portable electronic device. The 2 mm x 2 mm safety circuits protect a system from input over-voltage, over-current and battery over-voltage conditions, which may result from a power spike during charging, or a defective or incorrect wall adapter.

Texas Instruments has introduced three new smart battery management integrated circuits that improve measurement and protection of multi-cell, lithium-based battery packs. The innovative controllers simplify design in multi-cell lithium-based rechargeable batteries used in uninterruptible power supplies and applications, such as cordless power tools, power-assisted bicycles, and portable medical and test equipment.

Texas Instruments has introduced two integrated products designed to provide power and protection for USB ports. The TPS2500 and TPS2501 incorporate a boost switching regulator with an onboard current-limiting switch that saves space and cost by providing an integrated solution that meets 5-V USB power requirements from a 1.8 – 5.25 V input. The output current limit can be programmed via an external resistor from as low as 130 mA to as high...

Designers of mobile products routinely face the challenge of reducing space as well as improving efficiency in every aspect of their design. In devices that use a one-cell Li-Ion battery pack, such as ultraportable applications, this is an area of particular importance. To help designers meet the challenge of reducing design space and increasing efficiency, Fairchild Semiconductor has developed the FDMB2307NZ PowerTrench MOSFET. This device provi...

Fairchild Semiconductor has been named a winner in the annual Top-10 DC-DC Power Product Awards, hosted by Electronic Products China. This is the seventh time Fairchild has received this prestigious award, after submitting its FAN5400 USB-Compliant Li-Ion Battery Switching Charger for consideration by the panel of judges.

Fairchild Semiconductor provides designers of cell phones, datacards and netbooks a 6MHz synchronous Buck regulator that delivers high efficiency in a compact and razor-thin footprint. Higher switching frequencies typically lead to lower efficiencies. However, the FAN5361’s carefully optimized design mitigates these losses leading to 91 percent peak efficiency.
