Description The IL600 series are isolated signal couplers with CMOS or open drain transistor outputs which can be used to replace opto-couplers in many standard isolation functions. The devices are manufactured with NVE's patented IsoLoop(R) GMR sensor technology giving exceptionally small size and low power dissipation. A single resistor is used to set maximum input current for input voltages above 0.5 V. The devices are available in SOIC, PDIP and MSOP packages and as bare die.

Notes: 1. Absolute Maximum ambient operating temperature means the device will not be damaged if operated under these conditions. It does not guarantee performance. 2. 3. 4. PWD is defined as |tPHL - tPLH|. %PWD is equal to the PWD divided by the pulse width. tPSK is equal to the magnitude of the worst case difference in tPHL and/or tPLH that will be seen between units at 25C. The term VDD refers to the supply voltage on the output side of the isolated channel.

Operation The IL600 series are current mode devices. Changes in current flow into the input coil result in logic state changes at the output. One of the great advantages of the passive coil input is that both single ended and differential inputs can be handled without the need for reverse bias protection. The internal GMR sensor switches the output to logic low if current flows from (In-) to (In+). Only a single resistor is required to limit the input coil to the recommended 10 mA. This allows large input voltages to be used since there is no semiconductor structure on the input. The absolute maximum current through the coil of the IL600 series is 25 mA DC. However, it is important to limit input current to levels well below this in all applications. The worst case logic threshold current is 10 mA. While typical threshold currents are substantially less than this, NVE recommends designing a 10 mA logic threshold current in each application. In all cases, the current must flow from Into In+ in the coil to switch the output low. This is true regardless of true or inverted data configurations. Output logic high is the zero input current state. Figure 1 shows the response of the IL600 series. The GMR bridge structure is designed such that the output of the isolator is logic high when no field signal is present. The output will switch to the low state with 10 mA of coil current and the output will switch back to the high state when the input current falls below 2 mA. This allows glitchfree interface with low slew rate signals. should be noted that we are concerned only with the magnitude of the voltage across the coil. The absolute values of Vin High and Vin Low are arbitrary.
Figure 2. Series Resistor Calculation Equivalent Circuit. Example 1. In this case, Tnom = 25C, Vin High is 24 V, Vin Low is 1.8 V, and Icoil minimum is specified as 10 mA. Total loop resistance is (Vin High - Vin Low) 22.2 = = 2220 (R1 + Rcoil) = Icoil 0.01 Therefore, R1 = ( 2220 - 55) = 2145 Example 2. At a maximum operating temperature of 85C, Tmax = 85C, Tnom = 25C, Vin High = 5 V, Vin Low = 0 V, and nominal Rcoil = 55 . At Tmax = 85C Rcoil = 55 + ( Tmax - Tmin ) x TCRcoil
= 55 + (85 - 25) x 0.165 = 55 + 9.9 = 65 Therefore, the recommended series resistor is R1 = (VinHigh - VinLow) - Rcoil Icoil 5-0 = - 65 = 435 0.01
Allowance should also be made for the temperature coefficient of the current limiting resistor to ensure that Icoil is 10 mA at maximum operating temperature.
Figure 1. IL600 Series Transfer Function To calculate the value of the protection resistor (R1) required, use Ohm's law as shown in the examples below. It Power Supplies
It is recommended that 47 nF ceramic capacitors be used to decouple the power supplies. The capacitors must be placed as close as possible to VDD for proper operation.
