Agilent HCPL-7510 Isolated Linear Sensing IC Data Sheet 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 implementa-
tion, 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
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/
µs).
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.

Worldwide safety approval:
UL 1577 (3750 Vrms/1 min.) and
CSA (pending), DIN EN 60747-5-2
(Option #060 only pending)
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
The product can also be used for
general analog signal isolation
applications. For general
applications, we recommend the
HCPL-7510 (gain tolerance of
±3%). The HCPL-7510 utilizes
sigma delta (
-) 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, industry standard 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.
