Circuit forms adjustable bipolar clamp
The easy way to clamp a signal to a given value is to use two zener diodes, connected back-to-back. This method has several disadvantages...
Alpha and Omega Semiconductor Releases Fast Switching 600V αMOS5 Super Junction MOSFETs in SMD-type TOLL Package
Alpha and Omega Semiconductor announced the release of a Fast Switching 600 V αMOS5™ Super Junction MOSFETs in SMD-type TOLL Package. αMOS5 is AOS’s latest generation of high voltage MOSFET, designed to meet the high efficiency and high-density needs...
Circuit generates fan-speed control
Fan noise is becoming a significant issue as electronic equipment increasingly enters the office and the home. Noise is proportional to fan speed, and the airflow – hence, fan speed – necessary for cooling is less at low ambient temperatures...
Vishay Intertechnology's New Automotive Grade Proximity Sensors Deliver High Resolution Up to 20 µm for Force Sensing
The Optoelectronics group of Vishay Intertechnology introduced two new fully integrated Automotive Grade proximity sensors with high resolution up to 20 µm for force sensing applications...
Tips and tricks for optimizing your voltage supervisor
Voltage supervisors have provided analog voltage monitoring to digital circuits for decades. Texas Instruments released the original TL7705 in 1983; it consumed 1.8 mA, came in a plastic dual-inline package and you can still purchase it today...
Dialog Semiconductor Announces SLG47004 GreenPAK First Fully Programmable Advanced Analog System IC
Dialog Semiconductor announced the SLG47004, Dialog’s first Advanced Analog GreenPAK™ IC. The SLG47004 integrates an instrumentation amplifier with auto-trimming, digital pots, analog switches and a myriad of digital functions with in-system programmability in a small 3 mm × 3 mm solution size...
P-channel power-MOSFET driver uses unity-gain op amp
P-channel MOSFETs can simplify designs when you use them as high-side switches on circuits with voltages exceeding 100 V dc. When driving a MOSFET, you must rapidly charge and discharge the input capacitance between its gate and its source to reduce heat losses...
