Description

Product Overview

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 enables direct measurement of motor phase currents in power inverters by converting a low-bandwidth analog input into a high-speed one-bit data stream via Sigma-Delta modulation. Key advantages include high noise margins, excellent immunity against isolation-mode transients, and a 200 mV input range with a single 5V supply. Applications span motor phase and rail current sensing, data acquisition systems, industrial process control, and general-purpose current sensing.
