HCPL-7840-000E Description
The HCPL-7840 isolation amplifer family was designed for current sensing in
electronic motor drives. In a typical implementation, motor currents flow
through an external resistor and the resulting analog voltage drop is sensed
by the HCPL-7840. A differential output voltage is created on the other side of
the HCPL-7840 optical isolation barrier. This differential output voltage is
proportional to the motor current and can be converted to a single-ended
signal by using an op-amp as shown in the recommended application circuit.
Since common-mode voltage swings of several hundred volts in tens of
nanoseconds are common in modern switching inverter motor drives, the
HCPL-7840 was designed to ignore very high common mode transient slew rates
(of at least 10 kV/μs).
The high CMR capability of the HCPL-7840 isolation amplifer provides the
precision and stability needed to accurately monitor motor current in high
noise motor control environ-ments, providing for smoother control (less
“torque ripple”) in various types of motor control applications.
