... HCPL-7800(A). A differential output voltage is created on the other side of the HCPL-7800(A) optical isolation barrier. This differential output voltage is pro- portional to the motor current and can be converted to a single-ended signal by using an op-amp as shown in the recommended application circuit ...

... 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 HCPL- 7800(A) 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 ...

... HCPL-7800(A). The bypass capacitors are required because of the high-speed digital nature of the signals inside the HCPL-7800(A). 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 ...

... 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-7800(A); this minimizes the loop area of the connection and reduces the possibility of stray magnetic fields from interfering with the measured signal ...

... GND1 (pin 4), with the power-supply return path functioning as the sense line to the negative terminal of the current sense resistor. This allows a single pair of wires or PC board traces to connect the HCPL- 7800(A) circuit to the sense resistor. By referencing the input circuit to the negative side of the sense resistor, ...
