IL600 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 Coil Current The device switches to logic low if current flows from (In−) to (In+). mA Note that the designations “In−“ and “In+” refer to logic levels, not current flow. Positive values of current mean current flow into 5 the In− input. 3.5 Input Resistor Selection 1.5 Logic State t Resistors set the coil input current (see Figure 2). There is no limit to input voltages because there are no semiconductor input structures. High Worst-case logic low threshold current is 8 mA, which is for single- ended operation with a 3 V supply. In differential mode, where the Low input current reverses, the logic low threshold current is 5 mA for the range of supplies. A “boost capacitor” creates current reversals at edge t transitions, reducing the input logic low threshold current to the differential level of 5 mA. Figure 1. Typical IL600-Series Transfer Function Typical Resistor Values V 0.125W, 5% Resistor The table shows typical COIL I values for the external COIL 3.3 V 510  resistor for 5 mA coil VINH 5 V 820  R1 current. The values are approximate and should be adjusted for temperature or other application specifics. If the expected temperature range is large, 1% 85 Input tolerance resistors may provide additional design margin. Coil Single-Ended or Differential Input The IL610, IL611, IL613, and channel 1 of the IL614 can be run with VINL 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 Absolute Maximum recommended coil current in single-ended mode Equivalent Circuit 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). 9 NVE Corporation 11409 Valley View Road, Eden Prairie, MN 55344-3617 Phone: (952) 829-9217 Fax: (952) 829-9189 www.IsoLoop.com ©NVE Corporation

IL600 Series Isolators Non-inverting and Inverting Configurations IL600-Series Isolators can be configured in non- inverting and inverting configurations (see Figure 3). +5 V V DD In a typical non-inverting circuit, the In− terminal is connected via a 1 kΩ input resistor to the supply rail, C boo(cid:0)(cid:0)st 8 and the input is connected to the In+ terminal. The 820R (cid:0)(cid:0)IL610 7 C supply voltage is +5 V and the input signal is a 5 V 3 1 - 6 CMOS signal. When a logic high (+5 V) is applied to 2 + Data Out the input, the current through the coil is zero. When 5 the input is a logic low (0 V), at least 5 mA flows through the coil from the In− side to the In+ side. Data In The inverting configuration is similar to standard logic. In the inverting configuration, the signal into the coil is differential with respect to ground. The GND1 GND2 designer must ensure that the difference between the logic low voltage and the coil ground is such that the Non-Inverting Circuit Note: C is 47 nF ceramic. 11 residual coil current is less than 0.5 mA.

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 d V ) .

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 V pin. DD Maintaining Creepage Creepage distances are often critical in isolated circuits. In addition to meeting JEDEC standards, NVE isolator packages have unique creepage specifications. Standard pad libraries often extend under the package, compromising creepage and clearance. Similarly, ground planes, if used, should be spaced to avoid compromising clearance. Package drawings and recommended pad layouts are included in this datasheet. 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 NC V DD direction as the applied internal field. In one direction it will IN+ V H1 tend to help switching; in the other it will hinder switching. OE H2 This can cause unpredictable operation. IN- OUT An applied field in direction “H2” has considerably less effect NC GND and results in higher magnetic immunity. 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 Field applied in H1 direction ±20 Gauss 1 cm from the device could cause disturbance. A DC current of 56 A flowing in a conductor Field applied in H2 direction ±70 Gauss 1 cm from the device could cause disturbance. Field applied in any direction but with boost A DC current of 200 A flowing in a conductor ±250 Gauss capacitor (16 pF) in circuit 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 μs are more susceptible to magnetic fields than shorter pulse widths. 11 NVE Corporation 11409 Valley View Road, Eden Prairie, MN 55344-3617 Phone: (952) 829-9217 Fax: (952) 829-9189 www.IsoLoop.com ©NVE Corporation
