Description
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 10 kV/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−∆) 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).
