... HCPL-0872 Digital Interface IC or digital filter together form an isolated programmable two-chip analog-to-digital converter. The isolated modulator allows direct measure- ment of motor phase currents in power inverters. In operation, the HCPL-7860/HCPL-786J Isolated Modulator (optocoupler with 3750 V dielectric withstand voltage RMS rating) converts a low-bandwidth analog input into a high-speed one-bit data stream by means of a Sigma-Delta (Σ ...

... 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 kΩ ...
