Product Summary

The HCPL7520 is an isolated linear current sensing IC designed for current sensing in low-power electronic motor drives. An output voltage is created on the other side of the HCPL7520 optical isolation barrier. This single-ended output voltage is proportional to the motor current. The HCPL7520 was designed to ignore very high common-mode transient slew rates (of at least 10 kV/μs). The applications of the HCPL7520 include Low-power inverter current sensing, Motor phase and rail current sensing, Switched mode power supply signal isolation, General purpose low-power current sensing and monitoring and General purpose analog signal isolation.
