... R4 should be chosen to supply sufficient current from the existing floating supply. The voltage from the current sensing resistor (Rsense) is applied to the input of the ACPL-C78A/ C780/C784 through an RC anti-aliasing filter (R2 and C2). Although the application circuit is relatively simple, a few recommendations should be followed to ensure optimal performance ...

... 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 ACPL-C78A/C780/ C784; this minimizes the loop area of the connection and reduces the possibility of stray magnetic fields from inter- fering with the measured signal ...

... Frequently asked questions about the ACPL-C78A/C780/C784 1. The basics 1.1. Why should I use the ACPL-C78A/C780/C784 for sensing current when Hall-effect sensors are available which don’t need an isolated supply voltage? Available in an auto-insertable, Stretched SO-8 package, the ACPL-C78A/C780/C784 is smaller than and has better linearity, offset vs ...

... How do I ensure that the ACPL-C78A/C780/C784 is not destroyed as a result of short circuit conditions which cause voltage drops across the sense resistor that exceed the ratings of the ACPL- C78A/C780/C784’s inputs? Select the sense resistor so that it will have less than 5 V drop when short circuits occur ...
