Circuitos electrónicos: Current sense


pdfCurrent Sense Circuit Collection

Sensing and/or controlling current flow is a fundamental requirement in many electronics systems, and the techniques to do so are as diverse as the applications themselves. This Application Note compiles solutions to current sensing problems and organizes the solutions by general application type. These circuits have been culled from a variety of Linear Technology documents........

LM3423 Buck-Boost 2-Layer Low Side Current Sense Evaluation Board - LM3423BBLSCSEV - TI Tool Folder

This wide range evaluation board showcases the LM3423 NFET controller used with a buck-boost current regulator. It is designed to drive 4 to 8 LEDs at a maximum average LED current of 700 mA from a DC input voltage of 10 to 70V. The evaluation board showcases most features of the LM3423 including PWM dimming, fault and LED status flags, output overvoltage protection and input under-voltage lockout. It also has a connector footprint (J7) which can mate with an external LED load board allowing for.......

Circuit measures currents in dc servo motor - 2001-12-06 08:00:00 | EDN

The simple circuit design in Figure 1 lets you measure all components of a current flowing in a dc servo motor. The rectified output of the circuit uses ground as a reference, so you can measure the output by using a single-ended A/D converter. The current-sense resistor, R1, has a value of 0.
