The product provides the precision and stability needed to accurately monitor motor current in highnoise motor control environments, providing for smoother control (less “torque ripple”) in various types of motor control applications. This product paves the way for a smaller, lighter, easier to produce, high noise rejection, low cost solution to motor current sensing. The product can also be used for general analog signal isolation applications requiring high accuracy, stability and linearity under similarly severe noise conditions. For general applications, we recommend the HCPL-7800 which exhibits a part-to-part gain tolerance of ± 5%. For precision applications, HP offers the HCPL-7800A and HCPL-7800B, each with part-topart gain tolerances of ± 1%. The HCPL-7800 utilizes sigmadelta (Σ∆ ) analog-to-digital converter technology, chopper stabilized amplifiers, and a fully differential circuit topology fabricated using HP’s 1 µm CMOS IC process. The part also couples our high-efficiency, highspeed AlGaAs LED to a highspeed, noise-shielded detector Applications • Motor Phase Current Sensing • General Purpose Current Sensing • High-Voltage Power Source Voltage Monitoring *The terms common-mode rejection (CMR) and isolation-mode rejection (IMR) are used interchangeably throughout this data sheet.
