Introduction

AI Translation

The HCPL- 7520 isolated linear current sensing IC family is designed for current sensing in low- power electronic motor drives. In a typical implementation, motor current flows through an external resistor and the resulting analog voltage drop is sensed by the HCPL- 7520. An output voltage is created on the other side of the HCPL- 7520 optical isolation barrier. This single- ended output voltage is proportional to the motor current. Since common- mode voltage swings of several hundred volts in tens of nanoseconds are common in modern switching inverter motor drives, the HCPL- 7520 was designed to ignore very high common- mode transient slew rates (of at least 10kV / μs). The high CMR capability of the HCPL- 7520 isolation amplifier provides the precision and stability needed to accurately monitor motor current in high noise motor control environments, providing for smoother control (less "torque ripple") in various types of motor control applications. The product can also be used for general analog signal isolation applications. For general applications, we recommend the HCPL- 7520 (gain tolerance of ± 5%). The HCPL- 7520 utilizes sigma- delta (Σ - Δ) analog- to- digital converter technology to delivery offset and gain accuracy and stability over time and temperature. This performance is delivered in a compact, auto- insert, 8- pin DIP package that meets worldwide regulatory safety standards. (A gull- wing surface mount option 300 is also available).
