| Model Number : | HCPL-786J-000E |
The HCPL-7860/HCPL-786J Optically Isolated Modulator, when paired with the HCPL-0872 Digital Interface IC or a digital filter, forms a two-chip isolated programmable analog-to-digital converter. This system is designed for direct measurement of motor phase currents in power inverters. The HCPL-7860/HCPL-786J utilizes Sigma-Delta () over-sampling modulation to convert a low-bandwidth analog input into a high-speed one-bit data stream, offering high noise margins and excellent immunity to isolation-mode transients. The data and clock are transmitted across an isolation boundary for recovery and decoding. Key applications include motor phase and rail current sensing, data acquisition systems, industrial process control, and general-purpose current sensing and monitoring.
