Agilent HCPL-7510
Isolated Linear Sensing IC
Data Sheet
Description
The HCPL-7510 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-7510. An output
voltage is created on the other
side of the HCPL-7510 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-7510
was designed to ignore very
high common-mode transient
slew rates (of at least 10 kV/
s).
The high CMR capability of the
HCPL-7510 isolation amplifier
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.
Features

and IEC/EN/DIN EN 60747-5-2
(Option 060 only)
Advanced sigma-delta (
-)
A/D converter technology
Applications
Low-power inverter current
sensing
Motor phase and rail current
sensing
Switched mode power supply
signal isolation
General purpose low-power
current sensing and monitoring
General purpose analog signal
isolation
CAUTION: It is advised that normal static precautions be taken in handling and assembly of
this component to prevent damage and /or degradation which may be induced by ESD.
Functional Diagram
The product can also be used
for general analog signal
isolation applications. For
general applications, we
recommend the HCPL-7510
(gain tolerance of 5%). The
HCPL-7510 utilizes sigma delta
(S-D) 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 world-
wide regulatory safety
standards. (A gull-wing
surface mount option #300 is
also available).
