... HCPL-7860/HCPL-786J can be used together with HCPL- 0872, Digital Interface digital filter. The primary functions of the HCPL-0872 Digital Interface IC are to de- rive a multi-bit output signal by averaging the single-bit modulator data, as well as to provide a direct microcon- troller interface. The effective resolution of the multi-bit output signal is a function of the length of time (measured in modulator clock cycles) over which the average is taken ...

... R1 should be chosen to supply sufficient current from the existing floating sup- ply. The voltage from the current sensing resistor or shunt (Rsense) is applied to the input of the HCPL-7860/HCPL- 786J (U2) through an RC anti-aliasing filter (R2 and C2). And finally, the output clock and data of the isolated modulator are connected to the digital interface IC ...

For a two-terminal shunt, as the value of shunt resistance decreases, the resistance of the leads becomes a signifi- cant percentage of the total shunt resistance. This has two primary effects on shunt accuracy. First, the effective resis- tance of ...

... Shunt Connections The recommended method for connecting the isolated modulator to the shunt resistor is shown in Figure 17. V (pin 2 of the HPCL-7860/HCPL-786J) is connected to the positive terminal of the shunt resistor, while V shorted to GND1 with the power-supply return path func- tioning as the sense line to the negative terminal of the current shunt ...

... Voltage Sensing The HCPL-7860/HCPL-786J Isolated Modulator can also be used to isolate signals with amplitudes larger than its recommended input range with the use of a resistive volt- age divider at its input. The only restrictions are that the impedance of the divider be relatively small (less than 1 ...
