Electrical engineering in the 1960s: The transistor changed everything
13.02.2017 · Articles
The late 1950s and early 1960s saw perhaps the most dramatic change ever to hit electrical engineering. When transistors came along, many engineers needed to quickly learn how they worked and how to use them. Engineering managers had to convince upper management that transistors were the future of electronics. Herbert Pollack was one of those engineering managers...
Expanded Lineup of Transient Voltage Suppressors (TVS) XBP14E5UFN
13.02.2017 · News
Torex Semiconductor Ltd. has launched the XBP14E5UFN as a new series of transient voltage suppressors. The XBP14E5UFN series of transient voltage suppressors are mounted in close proximity to an external interface to protect downstream ICs from electrostatic discharge. Supporting high-speed signal lines with a low pin capacitance, the XBP14E5UFN is ideal for protection of USB 3.0, HDMI, and other lines...
Vishay Intertechnology Extends Capacitance Range of MIL-PRF-39006/33-Qualified Wet Tantalum Capacitor
13.02.2017 · News
Vishay Intertechnology announced that it has expanded the capacitance range of its M39006/33 tantalum-cased, hermetically sealed wet tantalum capacitor. Offering established reliability for critical avionics and aerospace systems, the device is the industry’s first such capacitor qualified to the MIL-PRF-39006/33 specification to offer capacitance from 15 µF to 680 µF over a wide voltage range from 50 V to 100 V...
Optocouplers are handy for motor drive
10.02.2017 · Circuits
Figure shows a latching circuit based on an optocoupler, IC1. If the off switch remains closed, pressing the on switch powers the LED in the optocoupler. Thus, the transistor in IC1 turns on. You can now release the on switch, and the transistor remains on...
AKM releases the Smallest Class Infrared Sensor IC in the World: the AK9752; capable of detecting through Glass and suitable as a Human Sensor
10.02.2017 · News
Recently the number of applications that use human presence sensors have increased, such as among IoT equipment. However, pyroelectric type sensors are hard to detect objects through glass. This was causing design constraints in the products. Asahi Kasei Electronics Corporation, (AKM), has developed the AK9752, a human presence sensor for short range applications, (detection distance about 1 m)...
Elmos: PSI5 interface IC for up to 24 sensors
09.02.2017 · News
Elmos is presenting a PSI5 interface IC with the E521.41. This component enables communication to the microcontroller over four channels with up to 6 sensors each. Data rates of 125 kbit/s or 189 kbit/s are used for data transmission to the controller. The transceiver conforms to the v1.3 and v2.1 PSI5 standards...
Derive a simple high-current source from a lab supply
08.02.2017 · Circuits
When electronic testing requires an adjustable current source, you must often build that piece of test equipment in the lab. You can easily make such a current source from a standard force-sense lab power supply. The circuit requires an additional power supply for the ICs and a separate control voltage...
Prototype to production: Arduino for the professional
08.02.2017 · Articles
Despite its popularity among hobbyists and electronics enthusiasts, the Arduino has become infamous among professional embedded systems developers. I must admit that for the longest time I also viewed the Arduino as so simple it was nearly useless for professional developers. But I have changed my mind. I’ve found that on a number of occasions over the last few years, rapid prototyping using Arduinos and Arduino shields has proven invaluable in moving a project forward...
