PRODUCT SHOWCASE Infrared dynamic gesture sensor from Maxim The MAX25405 optical sensor from Maxim uses infrared to recognise a variety of gestures (swipe, rotation etc). The MAX25405 has a sensing range up to 40cm, which makes it optimal for use in automotive applications such as car head units. Along with integrated optics and a 6x10 infrared sensor array, the MAX25405 includes a glass lens which increases sensitivity and improves the signal-to-noise ratio. The improved performance doubles the sensing range. This allows the other passengers in a car to use gesture-sensing entertainment displays. The MAX25405’s small 20-pin, 4x4x1.35mm QFN package comes together with four discrete LEDs, which ends up 75% smaller than comparable time-of-flight (ToF) camera-based solutions. It replaces multi-IC solutions, saving significant space. The MAX25405 IC and associated MAX25405EVKIT# evaluation kit are available now from Maxim Integrated and authorised distributors. For more information about Maxim Integrated’s MAX25405 gesture sensor, visit http://bit.ly/MAX25405Product Maxim Integrated www.maximintegrated.com/en.html Digi-Key launches myLists management system Digi-Key Electronics announced that it has launched a consolidated list management system, myLists, to streamline customers’ BOM Manager, price and availability, and favourites into one. Digi-Key is introducing myLists to make it easier for customers to manage their lists all in one place. In addition to providing greater convenience, myLists has over 15 features to benefit Digi-Key customers. The most notable features are an attrition calculator to plan for overages that account for parts lost or damaged during manufacturing, upload up to 1000 line items per list, list view customisation, and alternatives suggested in-line for parts when available. Other features also include: • Organise column order and data, and download it in a file • Differentiate lists and those shared with the user into two views • Add tags to assist with list management • Request pricing on six different quantities per part • Update filter options on the parts list • Define list preferences for part packaging: CT/TR or DKR/TR • Set preferences to manage quantities that do not meet requirements • Access to new data such as ECCN, HTSUS, country of origin and environmental information • Add notes to a part New products from Mouser Electronics In April, Mouser launched 3,069 new parts. Some of these new components include: Texas Instruments TMS570LS1227 16/32-Bit RISC flash micro The TI TMS570LS1227 is ideal for high-performance real-time control applications where safety is critical. The microcontroller family provides advanced safety architecture that includes dual CPUs in lockstep, CPU and memory BIST logic, ECC on both the flash and the data SRAM, and many more features. TE Connectivity NTSEAL 20-position connectors TE’s NTSEAL 20-position connectors provide flexible, robust wire-towire connectivity in a compact format for harsh environments with extreme siliconchip.com.au temperatures and vibrations. Applications include wire-to-wire, panel/ bulkhead mount, engine, chassis and automation. ROHM semiconductor BM6437xS-VA 600V IGBT modules The BM6437xS-VA intelligent power modules (IPMs) integrate gate drivers, bootstrap diodes, IGBTs and flywheel diodes. It has a collector current range of 15-35A and works as a 3-phase DC/ AC inverter. To see more of New Product Insider highlights, visit www.mouser.com/ newproductinsider/ Mouser Electronics Inc.
