This brushless motor driver targets applications requiring up to one-third horsepower and allows engineers the choice of either a DSP or an MCU digital interface. The unit's three independent half-bridges deliver up to 5A output current or 10A peak using industrial voltage supplies of 60V. Independent access to each of the six MOSFETs allows PWM control and commutation for three high-current outputs. Protection circuitry includes three-phase current monitoring, temperature monitoring, and prevention of shoot-through currents and activating both the top and the bottom MOSFETs in the same phase. The driver allows the use of smaller filter components by switching at frequencies up to 100 kHz. Offered in a 23-pin staggered-lead IC package, with a grounded case for easy heat-sinking, the SA305 operates over a temperature range of -40 to 85C.
Inforbix is leveraging its CAD and product data access technology to power up a free iPad app that lets mobile users search and access engineering data.
Unlike his friends in engineering programs, blogger Jon Titus had little need for calculus except in a few of his college physical-chemistry labs and classes.
In the wake of the Chevy Volt fire investigations, sales are down, and General Motors' (GM) CEO Dan Akerson is blaming the downturn on a spate of bad publicity.
Thanks to embedded electronics, medical devices are getting smaller and smarter than ever. Pacemakers and implantable defibrillators are now able to call physicians. MRIs, CT scanners, and ultrasound machines are gaining mobility. And the venerable Band-Aid may soon be able to detect illnesses ranging from fevers to heart arrhythmias. On February 21, join Design News senior editor Charles Murray for a wide-ranging discussion, "Embedded Angles for Medical Products," which will explore the latest developments in medical electronics. The discussion will examine advances in medical device technology and offer an inside look at the embedded electronics behind it.
