... In all cases, the current must flow from In to In+ in the coil to switch the output low. This is the case for true or inverted data, in single-ended or differential configurations. Output logic high is the zero input current state. Note that current flowing from Coil+ to Coil- (negative current in the specifications) will push the GMR sensor further into the high state ...

... V or 3.3 V output supplies. The specifications on pages 5 and 6 show the enhanced failsafe conditions available with the IL600A-Series Isolators that cover the non-open circuit condition. The output will remain in the state specified, or will switch to that state, if the specified current is flowing in the coil. Note that positive values of current mean current flow into the In input (pin 3 in Test Circuit 1) ...

In differential mode, erosion takes place in both directions as each current cycle reverses and has a net effect of zero up to the fuse current. A current of more than 100 mA will cause the coil to irreparably fuse ...

... Similarly, when using IL600A-Series devices, the designer should be aware that it is the voltage magnitude across the coil that creates the current, not just the value of the input voltage. To illustrate this point, consider the single-ended non-inverting and inverting cases. Bridge Output Response ...

... The IL612A does not offer inverting operation because the coil In inputs are internally hardwired 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 shield absorbs surrounding stray flux until it becomes saturated. At saturation the shield is transparent to external applied fields, and the GMR sensor may react to the field. To compensate for this effect, IsoLoop Isolators use Wheatstone Bridge structures that are only sensitive to differential magnetic fields. ...

... The circuit is intrinsically open circuit failsafe because the IL610A is guaranteed to switch to the high state when the coil input current is less than 500 µA. For higher speed, a faster output device (such the CMOS-output IL600-Series Isolators) are needed as well as possibly better impedance matching. 8 ...

... Multi-channel Isolated Alarm Monitor The open-drain outputs of IL600A-Series Isolators allow wired-OR outputs. The inputs can be configured for inverting or non- inverting operation (see Applications Information), and a very wide input voltage range is possible. This illustrative circuit provides fail-safe output (logic high output for zero coil current) and typical logic output sink current for each isolator. ...
