Agilent HCPL-7510
Isolated Linear Sensing IC
Data Sheet
Features
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/
碌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 鈥渢orque ripple鈥?
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-7510
(gain tolerance of 鹵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).
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.
