产品型号ISO150AU的概述

ISO150AU概述 ISO150AU是一款高性能的隔离型信号调理器,广泛应用于工业测量、过程控制、电力监控等领域。其主要功能是通过光隔离技术实现系统的安全隔离,确保高压与低压电路之间的有效分隔,进而提升系统的稳定性与安全性。ISO150AU的设计考虑了多种应用需求,例如宽输入范围、极低的失真和高共模抑制比等。 该芯片最显著的特点是其优异的隔离性能,能够保护敏感设备免受高电压信号的影响。此外,ISO150AU还具备较低的功耗,适合于电池供电的系统。其广泛的应用领域,包括但不限于空调控制、运动控制及自动化仪表等。 详细参数 ISO150AU的具体参数如下: - 工作电源电压(VDD):5V ±10% - 工作温度范围:-40°C至+85°C - 输入电流(Iinmax):±10mA - 输出电压:可在0V至VDD范围内 - 隔离电压:2500Vrms(在1分钟内) - 增益带宽产品:2M...

DESCRIPTION  
The ISO150 is a two-channel, galvanically isolated  
data coupler capable of data rates of 80MBaud, typi-  
cal. Each channel can be individually programmed to  
transmit data in either direction.  
ISO150 avoids the problems commonly associated  
with optocouplers. Optically isolated couplers require  
high current pulses and allowance must be made for  
LED aging. The ISO150’s Bi-CMOS circuitry oper-  
ates at 25mW per channel.  
Data is transmitted across the isolation barrier by  
coupling complementary pulses through high voltage  
0.4pF capacitors. Receiver circuitry restores the pulses  
to standard logic levels. Differential signal transmis-  
sion rejects isolation-mode voltage transients up to  
1.6kV/µs.  
ISO150 is available in a 24-pin DIP package and in a  
28-lead SOIC. Both are specified for operation from  
–40˚C to 85˚C.

This integrated circuit can be damaged by ESD. Burr-Brown

ESD damage can range from subtle performance degradation  
to complete device failure. Precision integrated circuits may  
be more susceptible to damage because very small parametric  
changes could cause the device not to meet its published

Conventional isolation barrier testing applies test voltage far  
ISOLATION BARRIER  
in excess of the rated voltage to catastrophically break down  
a marginal device. A device that passes the test may be  
weakened, and lead to premature failure.  
Data is transmitted by coupling complementary logic pulses  
to the receiver through two 0.4pF capacitors. These capaci-  
tors are built into the ISO150 package with Faraday shield-  
ing to guard against false triggering by external electrostatic  
fields.  
APPLICATIONS INFORMATION  
The integrity of the isolation barrier of the ISO150 is  
verified by partial discharge testing. 2400Vrms, 60Hz, is  
applied across the barrier for one second while measuring  
any tiny discharge currents that may flow through the  
barrier. These current pulses are produced by localized  
ionization within the barrier. This is the most sensitive and  
reliable indicator of barrier integrity and longevity, and does  
not damage the barrier. A device fails the test if five or more  
current pulses of 5pC or greater are detected.  
Figure 1 shows the ISO150 connected for basic operation.  
Channel 1 is configured to transmit data from side B to A.  
Channel 2 is set for transmission from side A to B. The R/T pins  
for each of the four transceivers are shown connected to the  
required logic level for the transmission direction shown. The  
transmission direction can be controlled by logic signals  
applied to the R/T pins. Channel 1 and 2 can be independently  
controlled for the desired transmission direction.

LOGIC LEVELS  
PROPAGATION DELAY AND SKEW  
A single pin serves as a data input or output, depending on  
the mode selected. Logic inputs are CMOS with thresholds  
set for TTL compatibility. The logic threshold is approxi-  
mately 1.3V with 5V supplies and with approximately 400mV  
of hysteresis. Input logic thresholds vary with the power  
supply voltage. Drive the logic inputs with signals that swing  
the full logic voltage swing. The ISO150 will use somewhat  
greater quiescent current if logic inputs do not swing within  
0.5V of the power supply rails.  
Logic transitions are delayed approximately 27ns through  
the ISO150. Some applications are sensitive to data skew—  
the difference in propagation delay between channel 1 and  
channel 2. Skew is less than 2ns between channel 1 and  
channel 2. Applications using more than one ISO150 must  
allow for somewhat greater skew from device to device.  
Since all devices are tested for delay times of 20ns min to  
40ns max, 20ns is the largest device-to-device data skew.  
MODE CHANGES  
In receive mode, the data output can drive 15 standard  
LS-TTL loads. It will also drive CMOS loads. The output  
drive circuits are CMOS.  
The transmission direction of a channel can be changed “on  
the fly” by reversing the logic levels at the channel’s R/T  
pins on both side A and side B. Approximately 75ns after the  
transceiver is programmed to receive mode its output is  
initialized “high”, and will respond to subsequent input-side  
changes in data.  
POWER SUPPLY  
Separate, isolated power supplies must be connected to side  
A and side B to provide galvanic isolation. Nominal rated  
supply voltage is 5V. Operation extends from 3V to 5.5V.  
Power supplies should be bypassed close to the device pins  
on both sides of the isolation barrier.  
STANDBY MODE  
Quiescent current of each transceiver circuit is very low in  
transmit mode when input data is not changing (1nA typi-  
cal). To conserve power when data transmission is not  
required, program both side A and B transceivers for trans-  
mit mode. Input data applied to either transceiver is ignored  
by the other side. High speed data applied to either trans-  
ceiver will increase quiescent current.  
The VS pin for each side powers the transceivers for both  
channel 1 and 2. The specified supply current is the total of  
both transceivers on one side, both operating in the indicated  
mode. Supply current for one transceiver in transmit mode  
and one in receive mode can be estimated by averaging the  
specifications for transmit and receive operation. Supply  
current varies with the data transmission rate—see typical  
curves.  
CIRCUIT LAYOUT  
The high speed of the ISO150 and its isolation barrier  
require careful circuit layout. Use good high speed logic  
layout techniques for the input and output data lines. Power  
supplies should be bypassed close to the device pins on both  
sides of the isolation barrier. Use low inductance connec-  
tions. Ground planes are recommended.  
POWER-UP STATE  
The ISO150 transmits information across the barrier only  
when the input-side data changes logic state. When a trans-  
ceiver is first programmed for receive mode, or is powered-  
up in receive mode, its output is initialized “high”. Subse-  
quent changes of data applied to the input side will cause the  
output to properly reflect the input side data.  
Maintain spacing between side 1 and side 2 circuitry equal  
or greater than the spacing between the missing pins of the  
ISO150 (approximately 16mm for the DIP version). Sockets  
are not recommended.  
SIGNAL LOSS  
The ISO150’s differential-mode signal transmission and  
careful receiver design make it highly immune to voltage  
across the isolation barrier (isolation-mode voltage). Rapidly  
changing isolation-mode voltage can cause data errors. As  
the rate of change of isolation voltage is increased, there is  
a very sudden increase in data errors. Approximately 50% of  
ISO150s will begin to produce data errors with isolation-  
mode transients of 1.6kV/µs. This may occur as low as  
500V/µs in some devices. In comparison, a 1000Vrms, 60Hz  
isolation-mode voltage has a rate of change of approximately  
0.5V/µs.  
Still, some applications with large, noisy isolation-mode  
voltage can produce data errors by causing the receiver  
output to change states. After a data error, subsequent changes  
in input data will produce correct output data.
