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/

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.

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.

Data Sheet

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).
