... In a typical implementation, motor current flows through an external resistor and the resulting analog voltage drop is sensed by the HCPL-7520. An output voltage is created on the other side of the HCPL- 7520 optical isolation barrier. This single-ended output voltage is proportional to the motor current. Since ...

... The voltage from the current sensing resistor (Rsense) is applied to the input of the HCPL-7520 through an RC anti-aliasing filter (R2 and C2). Although the application circuit is relatively simple, a few recom- mendations should be followed to ensure optimal performance. ...

... HCPL-7520. The bypass capacitors are required because of the high-speed digital nature of the signals inside the HCPL-7520. A 0.01 µF bypass capacitor (C2) is also rec- ommended at the input due to the switched-capacitor nature of the input circuit. The input bypass capacitor ...

... Smaller sense resistance decreases power dissipation, while larger sense resistance can improve circuit accuracy by utilizing the full input range of the HCPL -7520. The first step in selecting a sense resistor is determining how much current the resistor will be sensing. The graph in Figure 18 shows the RMS current in each phase of a ...

... The Kelvin connections to the resistor should be brought together under the body of the resistor and then run very close to each other to the input of the HCPL-7520; this minimizes the loop area of the connection and reduces the possibility of stray magnetic fields from in- terfering with the measured signal ...

... The only other require- ment is to shut down the drive before the sense resistor is damaged or its solder joints melt. This ensures that the input of the HCPL-7520 can not be damaged by sense resistors going open-circuit. 3. ISOLATION AND INSULATION 3 ...
