Isolated Current Sensing Module with ACPL-C79X

User Guide

Introduction

The ACPL-C79x isolated current sense evaluation module,

shown in Figure 1, is pin-to-pin compatible with several

Hall eect current transducers. The evaluation module has

a ±1% (ACPL-C79A) isolation amplier gain accuracy, but

the ACPL-C79x is also oered with a ±0.5% (ACPL-C79B)

or ±3% (ACPL-C790) specication. The ACPL-C79B/C79A/

C790 isolation ampliers were designed for current and

voltage sensing in electronic power converter, motor

drive and renewable energy applications.

For many compact power drive designs, a shunt resistor

plus isolation amplier measurement solution has many

benets over traditional Hall eect current sensors. The

benets include a smaller, lower prole component with

better linearity, lower temperature drift, and lower cost.

As shown in Figure 2, the evaluation module is 20 mm by

16 mm and 24 mm high.

Key components, including the shunt resistor and isola-

tion amplier, are available in small surface mount pack-

ages. Some designers who are familiar with current trans-

ducers can nd using the shunt resistor plus optically

isolated isolation amplier a challenge. This evaluation

module makes the evaluation quick and very easy.

The evaluation module is pin-to-pin compatible with se-

lected Hall eect current transducers, such as LEM’s LTS

6-NP, LTS 15-NP, LTS 25-NP, CAS 6-NP, CAS 15-NP, and CAS

25-NP models

[1]

. With the evaluation module, designers

using the LTS and CAS devices will nd it easy to evaluate

and compare the ACPL-C79X based current sensing solu-

tion against their existing Hall eect current transducer

solutions. For example, a designer can simply remove an

LTS 15-NP device and plug in the evaluation module and

start a quick evaluation.
