Description

Features

ꢄ

2ꢀ ꢁain Tolerance @ 25°C

The ACPL-782T isolation ampliﬁer was designed for

voltage and current sensing in electronic motor drives

and battery system monitoring. In a typical implementa-

tion, and motor currents ﬂow through an external resistor

and the resulting analog voltage drop is sensed by the

ACPL-782T. A diﬀerential output voltage is created on the

other side of the ACPL-782T 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 ap-

plication circuit. Since common-mode voltage swings

of several hundred volts in tens of nanoseconds are

common in modern switching inverter motor drives, the

ACPL-782T was designed to ignore very high common-

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

– IEC 60747-5-5, DIN EN 60747-5-2(VDE 0884 Teil 2)

ꢄ Qualiﬁed to AEC-Q100 Test ꢁuidelines

ꢄ Automotive Operating Temperature -40 to 125°C

ꢄ Advanced Sigma-Delta (ꢁꢂꢃ) A/D Converter Technology

ꢄ Fully Diﬀerential Circuit Topology

The high CMR capability of the ACPL-782T isolation

ampliﬁer provides the precision and stability needed to ac-

curately monitor motor current and DC rail voltage in high

noise motor control environments, providing for smoother

control(less“torqueripple”)invarioustypesofmotorcontrol

applications.

Applications

ꢄ Automotive Motor Inverter Current/Voltage Sensing

ꢄ Automotive AC/DC and DC/DC converter Current/

Voltage sensing

The product can also be used for general analog signal

isolation applications requiring high accuracy, stability,

and linearity under similarly severe noise conditions. The

ACPL-782T utilizes sigma delta (ꢁꢂꢃ) analog-to-digital

converter technology, chopper stabilized ampliﬁers, and

a fully diﬀerential circuit topology.

ꢄ Automotive Battery ECU

ꢄ Automotive Motor Phase Current Sensing

ꢄ Isolation Interface for Temperature Sensing

ꢄ ꢁeneral Purpose Current Sensing and Monitoring

Functional Diagram

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-insert-

able, industry standard 8-pin DIP package that meets

worldwide regulatory safety standards. (A gull-wing

surface mount option -300E is also available).

Avago R Coupler isolation products provide the rein-

SHIELD

forced insulation and reliability needed for critical in auto-

motive and high temperature industrial applications.

The connection of a 0.1 ꢀF bypass capacitor between

pins 1 and 4, pins 5 and 8 is recommended.

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.
