Description

The IL3285 and IL3222 are galvanically isolated, differential bus transceivers designed for bidirect ional data communication over balanced transmission lines. The devices use NVE’s patented* IsoLoop spintronic Gian t Magnetoresistance (GMR) technology. The IL3285 delivers at least 1.5 V into a 54 Ω load, and the IL3222 at least 2 V into a 100 Ω load for excellent data integrity over long cables. These devices are also compatible with 3.3 V input supplies, allowing interface to standard microcontrollers without additional level shifting. A unique ceramic/polymer composite barrier provides excellent isolation and virtually unlimited barrier life. Both the IL3285 and IL3222 have current limiting an d thermal shutdown features to protect against output short cir cuits and bus contentions that may cause excessive power dissipation. The receivers also incorporate a “fail -safe if open” design, ensuring a logic high on R if the bus lines are disconnected or “floating.” Receiver input resistance of 96 k Ω is eight times the RS-485 “Unit Load” (UL) minimum of 12 k Ω. Thus these products are known as “one-eighth UL” transceivers. There can be up to 256 on a network while still complying with the RS-485 loading specification.

Proper biasing can ensure fail-safe operation, that is a known state when there are no active drivers on the bus. IL3285 and IL3222 Isolated Transceivers include internal pull-up and pull-down resistors of approximately 200 kΩ in the receiver section (R FS-INT ; see figure on following page). These internal resistors are designed to ensure failsafe operation but only if there are no termination resistors. The entire V DD will appear between inputs “A” and “B” if there is no loading and no termination resistors, and there will be more than the required 200 mV with up to four RS -485/RS-422 worst-case one-eighth unit loads of 96 kΩ. Many designs operating below 1 Mbps or less than 1,000 feet are unterminated. Termination resistors may not be nece ssary for very low data rates and very short cable runs because reflections have time to settle before data sampling, which occurs at the middle of the bit interval. In busses with low-impedance termination resistors, however, the differential voltage across the conductor pair will be close to zero with no active drivers. In this case the state of the bus is indeterminate, and the idle bus will be susceptible to noise. For example, with 120 Ω termination resistors (R T) on each end of the cable, and four eighth unit lo ads (96 kΩ each), without external fail-safe biasing resistors the internal pull-up and pull-down resistors will produce a voltage between inputs “A” and “B” of only about one millivolt. This is not nearly enough to e nsure a known state. External fail-safe biasing resistors (R FS-EXT ) at one end of the bus can ensure fail-safe operation with a termi nated bus. Resistors should be selected so that under worst-case power supply and resistor tolerances there is at least 200 mV ac ross the conductor pair with no active drivers to meet the input sensitivity specification of the RS-422 and RS-485 standards. Using the same value for pull-up and pull-down biasing resistors maintains balance for positive- and negative going transitions. Lower-value resistors increase inactive noise immun ity at the expense of quiescent power consumption. Note that each Unit Load on the bus adds a worst-case loading of 12 kΩ across the conductor pair, and 256 one-eighth unit loads add 375 Ω worst-case loading. The more loads on the bus, the lower the r equired values of the biasing resistors. In the example with two 120 Ω termination resistors and four eighth unit loads, 560 Ω external biasing resistors provide more than 200 mV between “A” and “B” with adequate margin for power supply variations and resistor tolerances. This ensures a known state when there are no active drivers.
