Current sense - Circuitos electrónicos
Circuitos electrónicos: Current sense
Current sensor, to sense amount of current through a circuit, by sensing voltage drop across a resistor or voltage induced in a current carrying conductor
This article describes the fundamentals of and differences between high-side current sense amps, current monitors and protection circuits, hot-swap controllers, fuel gauges and battery management circuits, dynamic power-supply controllers, and advanced power-sensing circuits.
There are many choices of sensing elements to measure current to a load, and the choices of current sensing elements can be sorted by applications, as well as the magnitude of the current measured.No one sensor is the perfect solution for all applications because for every positive about a sensing element, there's a drawback. This white paper from Intersil provides an in-depth analysis of three different types of current sensing elements. It focuses on evaluating current measurements using a shu.......

High-wattage appliances like electric irons, ovens and heaters result in unnecessary power loss if left on for hours unnoticed. Here is a circuit that senses the flow of current through the appliances and gives audible beeps every fifteen minutes to remind you of power-on status. This is a non-contact version of current monitor and can sense the flow of current in high-current appliances from a distance of up to 30 cm . It uses transistors in the input to provide very high inp.......

Basic Interview Question Electrical interview questions:Different between megger and contact resistance meter? Answers:Megger used to measure cable resistance, conductor continuity, phase identification where as contact resistance meter used to measure low resistance like relays , contactors. Electrical interview questions :When we connect the capacitor bank in series ?Answers:we connect capacitor bank in series to improve the voltage profile at the load end in transmission line there is conside.......
TPS40060EVM is a wide input range synchronous buck converter using the full input range of the TPS40060 to produce a regulated 3. 3 V output at up to 4 A of load current. Using lossless RDS(on) current sense for short circuit protection and a high-side P-channel MOSFET simplifies the circuit design without sacrificing performance. The evaluation module provides test points for input voltage, output voltage, key waveforms and a 50 Ohm connection point in the feedback loop for non-invasive measure.......

The final part of the lap timer build along is also the easiest part, involving only the IR Detector and an optional LED with current limiting resistors. The previous steps can be found in the project index section of RC Arduino -http://rcarduino.blogspot.com/p/project-index. htmlA good introduction to IR Detectors is provided on the Ada Fruit website here -http://learn. adafruit.com/ir-sensorTo start our build we need a small section of strip board and a set of three wires for power, ground and.......
Apologies for the long delay in posting. . . I'm currently writing 3 books and all of them seem to have had major chapters due on the same day this past week. . . and before you say "Are ya crazy?! 3 Books!" - I've got a fourth book that started yesterday and a fifth book looking to start in a month. It's insane. (Fortunately 2 of my current books are looking like they'll finish in the next week or two. . . but still. . . )I've also been working on a "very special project" - Arduino-related, of .......
