Description

Features

 1ꢀ kV/μs common-mode rejection at V_CM= 1000 V

 Compact, auto-insertable standard 8-pin DIP package

The HCPL-7840 isolation ampliﬁer family was designed

for current sensing in electronic motor drives. In a typical

implementation, motor currents ﬂow through an external  0.0002ꢀ V/V/°C gain drift vs. temperature

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

 0.3 mV input oﬀset voltage

 100 kHz bandwidth

 0.0045 nonlinearity

 Worldwide safety approval:

UL 1ꢀ77 (37ꢀ0 Vrms/1 min.)

and CSA, IEC/EN/DIN EN 60747-ꢀ-2

 Advanced Sigma-Delta (∑-Δ) A/D converter technol-

ogy

HCPL-7840 was designed to ignore very high common-  Fully diﬀerential circuit topology

mode transient slew rates (of at least 10 kV/μs).

 0.8 μm CMOS IC technology

The high CMR capability of the HCPL-7840 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.

Applications

 Motor phase and rail current sensing

 Inverter current sensing

 Switched mode power supply signal isolation

 General purpose current sensing and monitoring

 General purpose analog signal isolation

The product can also be used for general analog signal

isolation applications requiring high accuracy, stability,

and linearity under similarly severe noise con-ditions. For

general applications, we recommend the HCPL-7840 (gain

tolerance of ꢀ5). The HCPL-7840 utilizes sigma delta

(∑-Δ) analog-to-digital converter technology, chopper

stabilized ampliﬁers, and a fully diﬀerential circuit topol-

ogy fabricated using Avago’s 0.8 μm CMOS IC process.

Together, these features deliver unequaled isolation-

mode noise rejection, as well as excellent oﬀset and gain

accuracy and stability over time and temperature. This

performance is delivered in a compact, auto-insertable,

industry standard 8-pin DIP package that meets world-

wide regulatory safety standards. (A gull-wing surface

mount option #300 is also available).

SHIELD

A 0.1 μF bypass capacitor must be connected

between pins 1 and 4 and between pins ꢀ and 8.

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.
