These high speed isolated calibrated current sensors are presented as an effective alternative to conventional shunt based solutions; standard-footprint packaged ICs simultaneously offer 100 kHz bandwidth, high accuracy and crosstalk resilience. By Graham Prophet @...

aimtec.com has a basic article on how to limit inrush current using passive components. Inrush current or input surge current refers to the maximum, instantaneous input current drawn by an electrical device during its initial turn on. Power converters also feature high inrush...

"baldengineer" explains which way the current flows. A couple of weeks ago I wrote about four current flow direction myths. As a follow up to that popular post, I decided to dedicate this month’s AddOhms electronics tutorial video to Current Flow. In episode #19, I tackle the...

Tiny Bar-Graph current meter displays a Red color bright, easy to read display of current range from 0 to 1A.  This Bar-Graph has 20 segments in single color and display 0 to 1Amp Current. The Barograph current monitor is based on PIC microcontroller with 10 Bit resolution ADC. ...

Peter Demchenko @ edn.com This Design Idea circuit regulates the current through one or more LEDs, making it almost independent of supply voltage. Its main advantage is a very small dropout voltage, which can be less than 100mV. The design could find use on LED strips, where the...

Allegro MicroSystems has released its first ever 1MHz bandwidth Hall-effect current sensor IC, boasting a 210ns response time. The ACS730 provides an economical and precise solution for AC or DC current sensing and is aimed at industrial, commercial, and communications systems for...

Maxim Integrated has posted details of the MAX44299, a low-side current, voltage, and power monitoring circuit that provides an analogue output current proportional to the measured current, voltage, and the internally calculated instantaneous power. The power monitor offers high...

Daniel Grießhaber @ hackaday.io has published his build of a USB power meter. His device is based on ATTiny 85 mcu and 0.96" OLED Display and is able to measure voltage, current and power output from USB port. Since USB has become more and more a power delivery standard, it...
