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 3.5 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. 1.5 Input Resistor Selection Coil Current mA 5 t Logic State High Low t Figure 1. Typical IL600-Series Transfer Function 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 singleended operation with a 3 V supply. In differential 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 the external resistor for 5 mA coil current. The values are approximate and should be adjusted for temperature or other application specifics. If the expected temperature range is large, 1% tolerance resistors may provide additional design margin. VCOIL 3.3 V 5V ICOIL VINH R1 85 Input Coil VINL 0.125W, 5% Resistor 510 820 Single-Ended or Differential Input The IL610, IL611, IL613, and channel 1 of the IL614 can be run with 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. Figure 2. Limiting Resistor Calculation Equivalent Circuit 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 electromigration 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 absolute 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). 8 IL600 Series Isolators Non-inverting and Inverting Configurations IL600-Series Isolators can be configured in noninverting and inverting configurations (see Figure 3). In a typical non-inverting circuit, the In- terminal is connected via a 1 k 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 current through the coil is zero. When the input is a logic low (0 V), at least 5 mA flows through the coil 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 the 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 inverting operation. The IL612 coil In- input is hardwired internally to the device power supply; therefore it is important 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. +5 V 820R Cboost IL610 VDD 8 7 3 2 + C1 6 Data Out 5 Data In GND1 GND2 Note: C1 is 47 nF ceramic.

Non-inverting and inverting circuits Boost Capacitor 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 driving the inputs. The instantaneous boost dV capacitor current is proportional to input edge speeds ( C dt ). 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. 1000 Signal Rise/Fall Time (ns) 500 3 16 2500 5000 CBoost (pF) Figure 4. Cboost Selector 9 IL600 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 Wheatstone 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 the 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. NC VDD IN+ IN- An applied field in direction "H2" has considerably less effect and results in higher magnetic immunity. NC VOE H2 H1 OUT GND 2. Differential Signaling 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 achieved by adding the boost capacitor. Method Approximate Immunity Immunity Description A DC current of 16 A flowing in a conductor 1 cm from the device could cause disturbance. Field applied in H1 direction 20 Gauss 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 direction 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 than 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 s are more susceptible to magnetic fields than shorter pulse widths. 10 IL600 Series Isolators Illustrative Applications V DD1 V DD2 V DD2 V DD1 8 8 R 1 ISL8485 IL610 ISL8490 2 3 1 + - RE 7 6 47nF R 5 47nF 47nF 8 IL610 B 7 D 3 4 2 6 + GND2 RE 7 6 47nF 6 R D Z 8 3 5 Y 5 IL610 17R 3 A 5 V DD3 17R 4 2 + RE 7 47nF 6 5 GND1 GND2 GND3 GND1 Isolated RS-485 and RS-422 Receivers Using IL610s IL610s can be used as simple isolated RS-485 or RS-422 receivers, terminating signals at the IL610 for a fraction of the cost of an isolated node. Cabling is simplified by eliminating the need to power the input side of the receiving board. No current-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. Placement of the current-limiting resistors on both lines provides better dynamic signal balance. There is generally no need for line termination resistors below data rates of approximately 10 Mbps because the IL610 coil resistance of approximately 85 is close to the characteristic impedance of most cables. The circuit is intrinsically open-circuit failsafe because the IL610 is guaranteed to switch to the high state when the coil input current is less than 0.5 mA. 11 Number of Nodes 1 2 3 4 5 8 Current Limit Resistors () None 17 22 27 27 27 30 3 R IL600 Series Isolators VDD1 VDD2 SJA1000 1 VDD1 8 VSS1 VSS2 RX1 22 20 VDD2 12 13 14 VDD2 18 C6 C5 C4 6 4 5 3 Cboost 4 Rs GND CANH Vcc CANL RXD Vref 8 7 6 5 1K PCA82C250 IL612 C3 C2 VDD3 TX0 TX1 2 2 8 7 VDD1 3 RX0 19 C1 1 21 TXD VSS3 15 Cboost Rs 1K GND1 GND2 Notes: Cboost is 16 pF ceramic All other capacitors are 47 nF ceramic Isolated CAN Bus Low pulse width distortion is critical for CAN bus, and IL600 Isolators are specified for just 3 ns typical pulse width distortion.
