Incorporating an algorithm that converts raw measurements like battery voltage, current and temperature in state of charge (%), absolute capacity (mAhr) and time-to-empty, time-to-full (while charging) values, the ModelGauge m5 standalone fuel gauge has been announced by Maxim Integrated.
Weartech-Components & Hardware
Audio jack detector and analogue switch are used in portable applications
Offering a space-saving alternative to miniQFN10 and WCSP devices, the Vishay Siliconix DG2592 audio jack detector and DG2750, low voltage, dual SPDT analogue switch have a slim profile of just 0.35mm and measure 1.4 x 1.8mm. Typical miniQFN10 and WCSP packages feature profiles of 0.55 mm. The thin miniQFN10 package of both devices is 36% thinner, allowing for slimmer handheld healthcare instruments, smartphones, tablets, portable media players, digital cameras, and wearable IoT devices. Compared to WCSP packages, the package is claimed to offer easier surface mounting and is better suited for the flexible PCBs commonly used in portable designs.
Automotive SoCs implement 3D graphics clusters
The first member of SoC in the R-Car family have been announced by Renesas. They can be used in 3D instrument cluster systems and provide a migration path as more automotive systems are expected to shift to 3D graphics instrument cluster systems in the near future.
Miniature SMT tact switch has operating force choices
Offering a package size of just 4.5 x 4.5mm, the TL3305 miniature SMT tact switch has a surface mount termination, and two operating forces to choose from. The switch from E-Switch has an operating lifecycle of up to 500,000. It also offers multiple actuator lengths from 3.8 to 7.0mm.
Applications include wearable technology, telecommunications, consumer electronics, audio/visual, medical devices, testing and instrumentation, computer and peripherals.
Electrical rating is 50mA at 12V DC, with a contact resistance of 100m? (max). Insulation resistance is 100M? (min) at 100V DC, with a dielectric strength of 250V AC for one minute. Operating temperature is -20 to 70°C.
