ELECTRONICS: Allegro MicroSystems’ new fully protected, single chip, full-bridge motor driver IC, the SPF7302, is for dc brush motor applications. This new solution enhances the user’s system reliability compared to other discrete solutions and is targeted at the automotive and industrial markets. The SPF7302 includes various integrated protection circuits and an externally adjustable delay timer to halt the OCL for proper motor startup. Open load detections are also present at start-up to ensure steady operation of the device. Other key features of this device include: overvoltage protection (OVP); overcurrent protection (OCP) with latch, which is adapted to the DMOSFETs in each full bridge; undervoltage lockout (UVLO); and overcurrent limitation. The package is a thermally enhanced 16-pin HSOP power package with an exposed thermal pad on the bottom side of the package. It is priced at $5.10 in quantities of 1,000.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
Healthcare might seem to be an unlikely target application for the Internet of Things technology, but recent developments show small ways that big-data is going to make an impact on patient care moving into the future.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
