Description

The IL600A-Series are isolated signal couplers with open-

drain outputs. They have a similar interface but better

performance and higher package density than optocouplers.

The devices are manufactured with NVE’s patented*

IsoLoop® spintronic Giant Magnetoresistiv e (GMR)

technology for small size, high speed, and low power.

A resistor sets the input current; a capacitor in parallel with

the current-limit resistor provides improved dynamic

performance.

These versatile components simplify inventory requirements

by replacing a variety of optocouplers, fu nctioning over a

wide range of data rates, edge speeds, and power supply

levels. The devices are available in MSOP, SOIC, and PDIP

packages, as well as bare die.

IL600A Series Isolators

Applications Information

IL600-Series Isolators are current mode devices. Changes in current flow into the input coil result in logic state changes at the

output. As shown in Figure 1, output logic high is the zero input current state.

Coil Polarity

The device switches to logic low if current flows from (In−) to

(In+).Note that the designations “In−“ and “In+” refer to logic levels,

not current flow. Positive values of current mean current flow into the

In− input.

Input Resistor Selection

Resistors set the coil input current (see Figure 2). There is no limit to

input voltages because there are no semiconductor input structures.

Worst-case logic low threshold current is 8 mA, which is for sing le-

ended operatio n wi t h a 3 V supply . I n di fferential mode, where the

input current reverses, the logic low threshold current is 5 mA for the

range of supplies. A “boost capacitor” creates current reversals at edge

transitions, reducing the input logic low threshold current to the

differential level of 5 mA.

Typical Resistor Values

The table shows typical

values for th e external

resistor for 5 mA coil

current. The values are

approximate and shou ld be adjusted for temper ature or other

application specifics. If th e expected temperature range is large, 1%

tolerance resistors may provide additional design margin.

Single-Ended or Differential Input

The IL610, IL61 1, IL 6 13 , an d c han nel 1 of t he IL6 14 can be ru n wi t h

single-ended or differential inputs (see Test Circuits on page 5). In the

differential mode, current will naturally flow through the coil in both

directions without a boost capacitor, although the capacitor can still be

used for increased external field immunity or improved PWD.

Absolute Maximum recommended coil current in single-ended mode

is 25 mA while differential mode allows up to ±75 mA to flow. The

difference in specifications is due to the risk of electromigrati on of

coil metals under constant current flow. In single ended mode, long-term DC current flow above 25 mA can cause erosion of the

coil metal. In differential mode, erosion takes place in both directions as each current cycle reverses and has a net effect of zero up

to the absolu te maximum current.

An advantage over optocouplers and other high-speed couplers in differential mode is that no reverse bias protection for the input

structure is required for a differential signal.

One of the more common applications is for an isolated Differential Line Receiver. For example, RS-485 can drive an IL610

directly for a fraction of the cost of an isolated RS-485 node (see Illustrative Applications).

Non-inverting and Inverting Configurations

IL600-Series Isolators can be configured in non-

inverting and inverting configurations (see Figure 3).

In a typical non-inverting circuit, the In− terminal is

connected via a 1 kΩ input resistor to the supply rail,

and the input is connected to the In+ terminal. The

supply voltage is +5 V and the input signal is a 5 V

CMOS signal. When a logic high (+5 V) is applied to

the input, the cu rrent through the coil is zero. When

the input is a logic low (0 V), at least 5 mA flows

through the co il from the In− side to the In+ side.

The inverting configuration is similar to standard

logic. In the inverting configuration, the signal into

the coil is differential with respect to ground. The

designer must ensure that the difference between the

logic low voltage and th e coil ground is such that the

residual coil current is less than 0.5 mA.

The IL612 and IL614 devices have some inputs that

do not offer inverti n g o perat ion. The IL612 coil In−

input is hardwired internally to the device power

supply; therefore it is importan t to ensure the isolator

power supply is at the same voltage as the power

supply to the source of the input logic signal. The

IL614 has a common coil In− for two inputs. This

pin should be connected to the power supply for the

logic driving channels 2 and 3, and the channels run

should be run in non-inverting mode.

Both single ended and differential inputs can be

handled without reverse bias protection.

Boost Capaci t or

The boost capacitor in parallel with the current-limiting resistor boosts the instantaneous coil current at the signal transition. This

ensures switching and reduces propagation delay and reduces pulse-width distortion.

Select the value of the boost capacitor based on the rise and fall

times of the signal drivin g t h e inpu ts. The instantaneous boost

capacitor current is proportional to input edge speeds ( ). Select a

capacitor value based on the rise and fall times of the input signal to be

isolated that provides approximately 20 mA of additional “boost”

current. Figure 4 is a guide to boost capacitor selection. For high-speed

logic signals (tr,tf < 10 ns), a 16 pF capacitor is recommended. The

capacitor value is generally not critical; if in doubt, choose a higher

value.

IL600A Series Isolators

Dynamic Power Consumption

Power consumption is proportional to duty cycle, not data rate. The use of NRZ coding minimizes power dissipation since no

additional power is consumed when the output is in the high state. In differential mode, where the logic high condition may still

require a current to be forced through the coil, power consumption will be higher than a typical NRZ single ended configuration.

Power Supply Decoupling

47 nF low-ESR ceramic capacitors are recommended to decouple the power supplies. The capacitors should be placed as close as

possible to the appropriate VDD pin.

Electromagnetic Compatibility and Magnetic Field Immunity

Because IL600-Series Isolators are completely static, they have the lowest emitted noise of any non-optical isolators.

IsoLoop Isolators operate by imposing a magnetic field on a GMR sensor, which translates the change in field into a change in

logic state. A magnetic shield and a Wheatston e Bridge configuration provide good immunity to external magnetic fields.

Immunity to external magnetic fields can be enhanced by proper orientation of the device with respect to the field direction, the

use of differential signaling, and boost capacitors.

1. Orientation of the device with respect to the field direction

An applied field in the “H1” direction is the worst case for

magnetic immunity. In this case th e external field is in the same

direction as the applied internal field. In one direction it will

tend to help switching; in the other it will hinder switching.

This can cause unpredictable operation.

An applied field in direction “H2” has considerably less effect

and results in higher magnetic immunity.

IN+ V

IN- OUT

NC GND

2. Differential Si gn al i ng and Boost Capacitors

Regardless of orientation, driving the coil differentially improves magnetic immunity. This is because the logic high state is driven

by an applied field instead of zero field, as is the case with single-ended operation. The higher the coil current, the higher the

internal field, and the higher the immunity to external fields. Optimal magnetic immunity is achieve d by adding the boost

capacitor.

Method Approximate Immunity Immunity Description

Field applied in H1 direction ±20 Gauss A DC current of 16 A flowing in a conductor

1 cm from the device could cause disturbance.

Field applied in H2 direction ±70 Gauss A DC current of 56 A flowing in a conductor

1 cm from the device could cause disturbance.

Field applied in any d irection but with boost

capacitor (16 pF) in circuit ±250 Gauss A DC current of 200 A flowing in a conductor

1 cm from the device could cause disturbance.

Data Rate and Magnetic Field Immunity

It is easier to disrupt an isolated DC signal with an external magnetic field th an it is to disrupt an isolated AC signal. Similarly, a

DC magnetic field will have a greater effect on the device than an AC magnetic field of the same effective magnitude. For

example, signals with pulses longer than 100 μs are more susceptible to mag netic fields than shorter pulse widths.

Isolated RS-485 and RS-422 Receivers Using IL610As

IL610As can be used as simple isolated RS-485 or RS-422 receivers, terminating signals at

the IL610A for a fraction of the cost of an isolated node. Cabling is greatly simplified by

eliminating the need to power the input side of the receiving board. No curre nt-limiting

resistor is needed for a single receiver because it will draw less current than the driver

maximum. Current limiting resistors allow at least eight nodes without exceeding the

maximum load of the transceiver chip. Placement of the current-limiting resistors on both

lines provides better dynamic signal b alance. There is no need for line termination resistor s

because the IL610A coil resistance of approximately 85 Ω is close to the characteristic

impedance of most cables. The circuit is intrinsically open circuit failsafe because the IL610A

is guaranteed to switch to the high state when the coil input current is less than 500 µA. For

higher speed, a faster output device (such the CMOS-output IL600-Series Isolators) are needed as well as possibly better

impedance matching.
