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 (PDIP) and you can still purchase it ...

A four-quadrant dc-dc converter offers an elegant way to control currents and voltages, and is able to set current to any level. While simple voltage converters can generate a fixed output voltage from an input voltage, this behavior isn’t ...

A switching regulator can be constructed either monolithically or via a controller. In a monolithic switching regulator, the respective power switches, usually MOSFETs, are integrated within a single silicon chip. With controllers, in addition to ...

Electronic Design I must be kidding, right? No, I’m not. I’m just suggesting that we take another look at the old programming language known as BASIC. The language has a great deal going for it, particularly that it’s easy to ...

Design Note 391 Introduction Handheld designers often grapple with ways to de-bounce and control the on/off pushbutton of portable devices. Traditional de-bounce designs use discrete logic, flip-flops, resistors and capacitors. Other designs ...

EDN As much as we’d prefer to be able to use just unforced, natural convection cooling, many designs and installations simply cannot be cooled adequately by the low level and uncertainty of airflow that this low-cost, reliable approach ...

Condition monitoring is one of today’s core challenges in the use of mechanical facilities and technical systems in which, for example, motors, generators, and gears are used. Planned maintenance is becoming more and more important for ...

Electronic Design By adding a resistive divider and dc voltage to a standard dc-dc regulator, you can easily develop dc rails below 1 V, all the way down to just a few hundred millivolts. You can generate a tiny dc supply voltage of a just a few ...

Electronic Design Proper component selection can help reduce startup time for gated oscillators. Gated oscillators always present the typical problem of having a delay when a digital input control signal enables its oscillation. This delay happens ...

In this article, I want to talk about the experience of repairing a OEM Harman/Becker audio amplifier, which was installed in Mercedes-Benz cars. In this particular case, it was a 2005 Mercedes, installed OEM audio amplifier Harman/Becker 7019 ...
