They have a similar interface but better performance and higher package density than optocouplers. The devices are manufactured with NVE's patented* IsoLoop(R) spintronic Giant Magnetoresistive (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, functioning over a wide range of data rates, edge speeds, and power supply levels.

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). 6 IL600A 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 3 VDD IL610A 8 7 - 6 2 + Data Out C1 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 capacitor current is proportional to input edge speeds ( C dV 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 7 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 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. 8 IL600A Series Isolators Illustrative Applications V DD1 V DD2 8 R ISL8485 1 C1 8 IL610A 7 D B/Z 3 4 6 2 A/Y 7 6 C2 R + 5 Cboost 5 GND1 Notes: Cboost is application specific All other capacitors are 47 nF ceramic GND2 Isolated RS-485 and RS-422 Receivers Using IL610As Number of Current Limit IL610As can be used as simple isolated RS-485 or RS-422 receivers, terminating signals at Nodes Resistors () the IL610A for a fraction of the cost of an isolated node. Cabling is greatly simplified by 1 None eliminating the need to power the input side of the receiving board. No current-limiting 2 17 resistor is needed for a single receiver because it will draw less current than the driver 3 22 maximum. Current limiting resistors allow at least eight nodes without exceeding the 4 27 maximum load of the transceiver chip. Placement of the current-limiting resistors on both 5 27 lines provides better dynamic signal balance. There is no need for line termination resistors 6 2 because the IL610A coil resistance of approximately 85 is close to the characteristic 7 30 impedance of most cables. The circuit is intrinsically open circuit failsafe because the IL610A 8 30 is guaranteed to switch to the high state when the coil input current is less than 500 A. For higher speed, a faster output device (such the CMOS-output IL600-Series Isolators) are needed as well as possibly better impedance matching.
