HCPL-7520-300E, Оптопара, усилители с оптической развязкой, 1 канал, Поверхностный Монтаж DIP, 8 вывод(-ов)

The HCPL-7520-300E is an isolated Linear Sensing IC designed for current sensing in servo drive applications. In a typical implementation, motor current flows through an external resistor and the resulting analogue voltage drop is sensed by the IC. An output voltage is created on the other side of the IC optical isolation barrier. The 1-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 IC was designed to ignore very high common-mode transient slew rates The high CMR capability of the isolation amplifier provides the precision and stability needed to accurately monitor motor current in high noise motor control environments, providing for smoother control in various types of motor control applications.
