PSMA Announces Reprint Availability of Lee’s Electronic Transformers and Circuits
The Power Sources Manufacturers Association (PSMA) is pleased to announce availability of the classic engineering text Electronic Transformers and Circuits – Third Edition Reprint, authored by the late Rueben Lee and co-authored by Leo Wilson and Charles E. Carter. The book was initially published by John Wiley and Sons in 1988, but has been out of print for several years. Copies of this practical design treatment of magnetics will be available...
Power Sources Manufacturers Association Reprints Classic Magnetics Text
The Power Sources Manufacturers Association (PSMA) announced that it is again making available Nathan Grossner's classic treatise, Transformers for Electronic Circuits - Second Edition. The first reprint of this work sold out and this second reprint is now available. PSMA members may now purchase this important text online, directly from PSMA, at the discounted price of $55. The non-member PSMA online price is $75. Non-members may also purchase i...
Two-wire Hall-effect unipolar switches offer improved high-voltage transient protection for automotive applications
The A1152/3/5/6 from Allegro MicroSystems Europe are a range of two-wire unipolar Hall-effect switches designed for automotive sensing applications in seat-belt buckle, seat position, and steering lock applications. The new devices are produced using the Allegro advanced BiCMOS wafer fabrication process, and include improved high-voltage transient protection: a critical factor for automotive applications where external protection circuitry canno...
Allegro MicroSystems, Inc. Introduces a New Family of Two-Wire, Hall-Effect Unipolar Switches Improved High Voltage Transient Protection
Allegro MicroSystems introduced a new line of two-wire, unipolar, Hall-effect switches to complement its existing family of devices used in seat belt buckle, seat position, and steering lock applications. These new devices are targeted to serve the automotive market, because they include improved high voltage transient protection, which is a feature that is critical for applications, which do not allow protection circuits to be located close to t...
Allegro MicroSystems - Hall-effect latches withstand high-voltage transients and high temperatures
The new A1225, A1227 and A1229 from Allegro MicroSystems Europe are a family of Hall-effect latch ICs that combine enhanced protection against high transient voltages with the ability to operate over extended temperature ranges up to +150°C.
User-programmable automotive linear sensor from Allegro
The new A1386 from Allegro MicroSystems Europe is a user-programmable linear Hall-effect sensor IC targeted at applications in the automotive market requiring flexibility and accuracy in absolute position sensing.
Ultra-sensitive dual-channel quadrature Hall-effect bipolar switch
The new A1230 from Allegro MicroSystems Europe is an ultra-sensitive dual-channel quadrature Hall-effect bipolar switch IC designed for use in rotating ring-magnet based speed and direction sensing applications in harsh automotive and industrial environments.
Allegro's A138X Programmable Hall sensor ICs are low profile
The new A138X family of Hall-effect sensor integrated circuits from Allegro MicroSystems Europe are programmable, analogue-output devices that are offered in a choice of low-profile surface-mount packages.
Precision linear Hall sensor for current and position sensing applications
The new A1351 from Allegro MicroSystems Europe is a high-precision linear Hall-effect sensor IC with a 125 Hz push/pull pulse-width-modulated (PWM) output that is proportional to an applied magnetic field. The A1351 converts an analogue signal from its internal Hall sensor element to a digitally encoded PWM output signal. The coupled noise immunity of the digitally encoded PWM output is far superior to the noise immunity of an analogue output sig...
Medical Power Supply From Excelsys Technologies
Excelsys Technologies has introduced the new Xzite 1200W modular power supply approved for use in medical applications. The Xzite family of low noise power supplies has measured background noise of just 59dBA while providing up to 1200 watts output in an extremely compact 1U x 260 x 127mm package.
