HCPL-7860-300E is an isolated 15-bit A/D converter. This isolated modulator allows direct measurement of motor phase currents in power inverters used in automotive applications. It converts a low-bandwidth analogue input into a high-speed one-bit data stream by means of a Sigma-Delta (Σ−∆) over-sampling modulator. This modulation provides for high noise margins and excellent immunity against isolation-mode transients. The modulator data and on-chip sampling clock are encoded and transmitted across the isolation boundary, where they are recovered and decoded into separate high-speed clock and data channels. Applications include motor phase and rail current sensing, DC bus voltage sensing, inverter current sensing, switched mode power supply signal isolation, general purpose current sensing and monitoring, general purpose analogue signal isolation, traditional hall effect current sensor replacement.
