Overview

The HCPL-7840 isolation amplifier family was designed for current sensing in electronic motor drives. In a typical implementation, motor currents fl ow through an external resistor and the resulting analog voltage drop is sensed by the HCPL-7840. A differential output voltage is created on the other side of the HCPL-7840 optical isolation barrier.

Applications ● Motor phase and rail current sensing ● Inverter current sensing ● Switched mode power supply signal isolation ● General purpose current sensing and monitoring ● General purpose analog signal isolation
