| When a lithium-ion battery is discharged below the minimum recommended cell voltage its life expectancy is dramatically reduced. The circuit...
| In the December issue we’ll describe a fancy Li-Ion charger based on a specially designed IC and boasting many bells and whistles. However,...
| ICs for measuring currents usually employ external sense resistors with values of a few tens of milliohms. Not only are such resistors diffi...
| It frequently happens that you have an application in which you want to measure the temperature of a circuit or the outside world. This can...
| If you say that the term ‘Opentherm’ is unfamiliar to you, then this will not surprise us the least. Opentherm is a protocol, which can cont...
| Nowadays, there is a whole series of switching regulator ICs that work according to the step-up principle and thus convert the input voltage...
| Some applications notes are real evergreens. This one originally dates from 1979(!) but has lost nothing of its relevance and is always very...
| This DC-to-DC converter delivers a maximum power of about 36 watts at an efficiency of 90%. Apart from a modern FET and a Schottky diode, th...
| A few months ago under this heading, we presented a number of Internet addresses for MP3 projects. Most of them are based on re-using hardwa...
