The I/O channel of the device consists of two internal data channels, a high-frequency channel (HF) with a bandwidth from 100 kbps up to 150 Mbps, and a low-frequency channel (LF) covering the range from 100 kbps down to DC. In principle, a single-ended input signal entering the HF-channel is split into a differential signal through the inverter gate at the input. The following capacitor-resistor networks differentiate the signal into transients, which then are converted into differential pulses by two comparators. The comparator outputs drive a NOR-gate flip-flop whose output feeds an output multiplexer. A decision logic (DCL) at the driving output of the flip-flop measures the durations between signal transients. If the duration between two consecutive transients exceeds a certain time limit, (as in the case of a low-frequency signal), the DCL forces the output-multiplexer to switch from the high- to the lowfrequency channel. Because low-frequency input signals require the internal capacitors to assume prohibitively large values, these signals are pulse-width modulated (PWM) with the carrier frequency of an internal oscillator, thus creating a sufficiently high frequency signal, capable of passing the capacitive barrier. As the input is modulated, a low-pass filter (LPF) is needed to remove the high-frequency carrier from the actual data before passing it on to the output multiplexer. 8.2 Functional Block Diagram 图 14.

Care should be taken to maintain the creepage and clearance distance of a board design to ensure that the mounting pads of the isolator on the printed-circuit-board (PCB) do not reduce this distance. Creepage and clearance on a PCB become equal in certain cases. Techniques such as inserting grooves and/or ribs on a PCB are used to help increase these specifications. 表 2.

A failure of the IO can allow low resistance to ground or the supply and, without current limiting, dissipate sufficient power to overheat the die and damage the isolation barrier, potentially leading to secondary system failures.

The power dissipation and junction-to-air thermal impedance of the device installed in the application hardware determines the junction temperature. The assumed junction-to-air thermal resistance in the Thermal Information table is that of a device installed on a high-K test board for leaded surface-mount packages. The power is the recommended maximum input voltage times the current. The junction temperature is then the ambient temperature plus the power times the junction-to-air thermal resistance. 500 450 400 350 300 250 200 150 100 50 0 VCC1 = VCC2 = 2.7V VCC1 = VCC2 = 3.6V VCC1 = VCC2 = 5.5V 0 50 100 150 200 o Case Temperature – C 图 15.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 9.1 Application Information ISO71xx use single-ended TTL-logic switching technology. Its supply voltage range is from 3 V to 5.5 V for both supplies, VCC1 and VCC2. When designing with digital isolators, it is important to note that due to the single-ended design structure, digital isolators do not conform to any specific interface standard and are only intended for isolating single-ended CMOS or TTL digital signal lines. The isolator is typically placed between the data controller (that is, μC or UART), and a data converter or a line transceiver, regardless of the interface type or standard. 9.2 Typical Applications 9.2.1 Isolated Data Acquisition System for Process Control ISO71xx combined with TI's precision analog-to-digital converter and mixed signal micro-controller can create an advanced isolated data acquisition system as shown in 图 17. 5 VISO ISO-BARRIER 5 VISO 5 VISO 0 .1 F 22 AVDD 11 RTD 12 16 1 0.1 F DVDD AIN1+ A0 AIN1- A1 SCLK Bridge 18 17 AIN2+ DOUT 13 14 16 Current shunt 15 7 13 27 12 28 11 ADS1234 AIN3+ 5VISO AIN3- REFGAIN0 GAIN1 AIN4+ AIN4AGND 21 SPEED PWDN 10 14 8 AIN2REF+ Thermo couple 3.3 V 3.3 V 0 .1 F 9, 15 5 VISO V CC2 VCC 1 EN2 EN1 INA OUTA OUTB ISO7141 OUTC IND GND2 INB INC OUTD GND1 0 .1 F 1 7 11 4 12 5 14 6 13 0.1 F 0.1 F 16 10 23 14 24 13 25 12 26 11 DGND 9, 15 V CC2 VCC 1 EN NC OUTA OUTB INA ISO7140 INB OUTC INC OUTD IND GND2 GND1 DVcc P 3.0 XOUT 3.3 V CLK MSP430 F2132 P3.7 SOMI P 3.4 1 7 XIN P3.6 15 5 P 3.1 2, 8 20 19 2 0.1 F 3 0.1 F DVss P3.5 6 18 17 16 4 3 4 5 6 2, 8 2 图 17.

The capacitors should be placed as close to the supply pins as possible. If only a single primary-side power supply is available in an application, isolated power can be generated for the secondary-side with the help of a transformer driver such as TI's SN6501. For such applications, detailed power supply design and transformer selection recommendations are available in SN6501 data sheet (SLLSEA0). 11 Layout 11.1 Layout Guidelines A minimum of four layers is required to accomplish a low EMI PCB design (see 图 25). Layer stacking should be in the following order (top-to-bottom): high-speed signal layer, ground plane, power plane and low-frequency signal layer. • Routing the high-speed traces on the top layer avoids the use of vias (and the introduction of their inductances) and allows for clean interconnects between the isolator and the transmitter and receiver circuits of the data link. • Placing a solid ground plane next to the high-speed signal layer establishes controlled impedance for transmission line interconnects and provides an excellent low-inductance path for the return current flow. • Placing the power plane next to the ground plane creates additional high-frequency bypass capacitance of approximately 100pF/in2. • Routing the slower speed control signals on the bottom layer allows for greater flexibility as these signal links usually have margin to tolerate discontinuities such as vias. If an additional supply voltage plane or signal layer is needed, add a second power / ground plane system to the stack to keep it symmetrical. This makes the stack mechanically stable and prevents it from warping. Also the power and ground plane of each power system can be placed closer together, thus increasing the high-frequency bypass capacitance significantly. For detailed layout recommendations, see Application Note SLLA284, Digital Isolator Design Guide. 11.1.1 PCB Material For digital circuit boards operating below 150 Mbps, (or rise and fall times higher than 1 ns), and trace lengths of up to 10 inches, use standard FR-4 epoxy-glass as PCB material. FR-4 (Flame Retardant 4) meets the requirements of Underwriters Laboratories UL94-V0, and is preferred over cheaper alternatives due to its lower dielectric losses at high frequencies, less moisture absorption, greater strength and stiffness, and its selfextinguishing flammability-characteristics. 11.2 Layout Example High-speed traces 10 mils Ground plane 40 mils Keep this space free from planes, traces , pads, and vias FR-4 0r ~ 4.5 Power plane 10 mils Low-speed traces 图 25.
