Texas Instruments Inc.'s DRV8412 is the first in a new line of scalable evaluation
platforms for spinning motors. The DRV8412 evaluation kit (DRV8412-C2-KIT) includes all of the hardware and software needed to spin
two brushed dc motors or a single stepper motor out of the box. This highly
integrated, robust solution speeds development time for brushed dc and stepper
motors running up to 6A continuous/12 A peak at 50V. Applications include
medical pumps, gate openers, stage lighting, textile manufacturing tools and
industrial or consumer robotics.
Modular control architecture offers flexibility to
choose the right level of processing performance for the application. In
addition to the C2000 controlCARD module, more TI MCU options will be
available in 2011.
DRV8412 motor driver with integrated MOSFETs enable up to 97-percent
efficient operation, and delivers 6A continuous/12A peak current at 50V without
the need for a costly heat sink. The DRV8412 motor driver also includes advanced
on-chip protection, including cycle-by-cycle over-current,
over-temperature and under-voltage protection, to reduce design complexity
and board space.
C2000 Piccolo MCU performs control, communications and debug. The
industry-leading 32-bit C2000 MCU integrates control peripherals and CPU capability
in an embedded MCU device family starting under $2. This includes access
to the most thorough set of motor control software modules, real-time
debug capabilities, and open-tooled reference designs via free controlSUITETM software.
C source code and easy-to-use GUI demonstrate voltage and
current control of one or two brushed DC motors, as well as speed and
index, including up to 128 microsteps, of a stepper motor.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
