pulse Multi-function integrated FET switch replaces automotive relays Infineon’s HITFET+ switch family features adjustable slew rate and outstanding protection features; the first family member BTF3050TE is now in high-volume production for replacement of electromechanical relays. The HITFET+ family are protected lowside switches;they comprise highly integrated temperature protected MOSFETs with a feature set including diagnosis function, digital status feedback and short-circuit robustness, and – not available until today – controlled slew rate adjustment for easily balancing switching losses and EMC compliance. The HITFET+ family will comprise at least 16 members varying in RDS(on) (10 to 800 mOhm), feature set (i.e. with and without status feedback), and package size (D-PAK with 5 or 3 pins, DSO with 8 pins). HITFET+ products of one package size are completely scalable: There is no need for system designers to change either software or PCB layout to drive various loads. The first family member, the BTF3050TE, is already available in high-volume. HITFET+ is aimed at a wide range of automotive and industrial applications whenever there is need for MOSFETs with protection functionality; in automotive applications, the HITFET+ products can drive solenoids for valve control with PWM (Pulse Width Modulation) up to 20 kHz. They suit automotive light dimming applications where they prevent flickering and support typical power levels of 10W to 60W. The HITFET+ family is suitable for a range of other automotive applications such as mid-size and small-size electric motor drives for door lock or parking brake; for injection valves for alternative fuel (LPG, CNG); flap driving in HVAC (heating ventilation and air-conditioning); rear wheel steering applications as well as safety relay replacement in active suspension systems. HITFET+ products are also suitable as protected drivers in a wide area of industrial applications such as printers; vacuum cleaners; solar power modules; and vending machines. Design win; IDT meets IKEA Integrated Device Technology, Inc. (IDT) has disclosed that IKEA has chosen IDT’s wireless power transmitters to embed in its furniture and accessories for convenient wireless charging of enabled portable devices. IDT’s P9030 magnetic induction transmitters are embedded in new IKEA products including side tables and lamps. The products will soon be available in stores throughout North America and Europe. In addition to the furniture, IKEA has developed a line of charging pads as well as a wireless charger that consumers can build into furniture themselves—all built around the IDT wireless power semiconductor devices. The P9030 transmitter complies with the Wireless Power Consortium’s (WPC) Qi standard, delivering a 5W single-chip solution in a compact package. IDT accommodates all major wireless charging standards and technologies with Complete article, here 11 EDN Europe | MAY 2015 www.edn-europe.com
