ISL32493E

±60V Fault Protected, 5V, RS-485/RS-422 Transceivers with ±25V CMR and ESD Protection ISL32490E, ISL32492E, ISL32493E, ISL32495E, ISL32496E, ISL32498E The ISL32490E, ISL32492E, ISL32493E, ISL32495E, Features ISL32496E, ISL32498E are fault protected, 5V powered, differential transceivers that exceed the RS-485 and RS-422 standards for balanced communication. The RS-485 transceiver pins (driver outputs and receiver inputs) are fault protected up to ±60V and are protected against ±16.5kV ESD strikes without latch-up. Additionally, the extended common mode range allows these transceivers to operate in environments with common mode voltages up to ±25V (>2x the RS-485 requirement), making this fault protected RS-485 family one of the most robust on the market. Transmitters (Tx) deliver an exceptional 2.5V (typical) differential output voltage into the RS-485 specified 54Ω load. This yields better noise immunity than standard RS-485 ICs or allows up to six 120Ω terminations in star network topologies. Receiver (Rx) inputs feature a “Full Fail-Safe” design that ensures a logic high Rx output if Rx inputs are floating, shorted, or on a terminated but undriven (idle) bus. Rx outputs have high drive levels; typically, 15mA @ VOL = 1V (for opto-coupled, isolated applications). Half duplex (Rx inputs and Tx outputs multiplexed together) and full duplex pinouts are available. See Table 1 on page 2 for key features and configurations by device number. For fault protected or wide common mode range RS-485 transceivers with cable invert (polarity reversal) pins, please see the ISL32483E data sheet. • Fault Protected RS-485 Bus Pins . . . . . . . . . . . . . .

TEST CIRCUIT FIGURE 8B. MEASUREMENT POINTS FIGURE 8. RECEIVER ENABLE AND DISABLE TIMES Application Information RS-485 and RS-422 are differential (balanced) data transmission standards used for long haul or noisy environments. RS-422 is a subset of RS-485, so RS-485 transceivers are also RS-422 compliant. RS-422 is a point-to-multipoint (multidrop) standard, which allows only one driver and up to 10 (assuming one-unit load devices) receivers on each bus. RS-485 is a true multipoint standard, which allows up to 32 one-unit load devices (any combination of drivers and receivers) on each bus. To allow for multipoint operation, the RS-485 specification requires that drivers must handle bus contention without sustaining any damage. Another important advantage of RS-485 is the extended common mode range (CMR), which specifies that the driver outputs and receiver inputs withstand signals that range from +12V to -7V. RS-422 and RS-485 are intended for runs as long as 4000 feet; thus, the wide CMR is necessary to handle ground potential differences, as well as voltages induced in the cable by external fields. The ISL3249xE is a family of ruggedized RS-485 transceivers that improves on the RS-485 basic requirements and thereby FN7786.0 January 18, 2011 11 ISL32490E, ISL32492E, ISL32493E, ISL32495E, ISL32496E, ISL32498E increases system reliability. The CMR increases to ±25V, while the RS-485 bus pins (receiver inputs and driver outputs) include fault protection against voltages and transients up to ±60V. Additionally, larger-than-required differential output voltages (VOD) increase noise immunity, while the ±16.5kV built-in ESD protection complements the fault protection. on the market. This level of protection makes the ISL3249xE perfect for applications where power (e.g., 24V and 48V supplies) must be routed in the conduit with the data lines, or for outdoor applications where large transients are likely to occur. When power is routed with the data lines, even a momentary short between the supply and data lines will destroy an unprotected device. The ±60V fault levels of this family are at least five times higher than the levels specified for standard RS-485 ICs. The ISL3249xE protection is active whether the Tx is enabled or disabled, and even if the IC is powered down. If transients or voltages (including overshoots and ringing) greater than ±60V are possible, then additional external protection is required. Receiver (Rx) Features These devices utilize a differential input receiver for maximum noise immunity and common mode rejection. Input sensitivity is better than ±200mV, as required by the RS-422 and RS-485 specifications. Receiver input (load) current surpasses the RS-422 specification of 3mA and is four times lower than the RS-485 “Unit Load (UL)” requirement of 1mA maximum. Thus, these products are known as “one-quarter UL” transceivers, and there can be up to 128 of these devices on a network while still complying with the RS-485 loading specification. The Rx functions with common mode voltages as great as ±25V, making them ideal for industrial or long networks where induced voltages are a realistic concern. All the receivers include a “full fail-safe” function that guarantees a high-level receiver output if the receiver inputs are unconnected (floating), shorted together, or connected to a terminated bus with all the transmitters disabled (i.e., an idle bus). Rx outputs feature high drive levels (typically 22mA @ VOL = 1V) to ease the design of optically coupled isolated interfaces. Receivers easily meet the data rates supported by the corresponding driver, and all receiver outputs are three-statable via the active low RE input. The Rx in the 250kbps and 1Mbps versions include noise filtering circuitry to reject high-frequency signals. The 1Mbps version typically rejects pulses narrower than 50ns (equivalent to 20Mbps), while the 250kbps Rx rejects pulses below 150ns (6.7Mbps). Widest Common Mode Voltage (CMV) Tolerance Improves Operating Range RS-485 networks operating in industrial complexes or over long distances are susceptible to large CMV variations. Either of these operating environments may suffer from large node-to-node ground potential differences or CMV pickup from external electromagnetic sources, and devices with only the minimum required +12V to -7V CMR may malfunction. The ISL3249xE’s extended ±25V CMR is the widest available, allowing operation in environments that would overwhelm lesser transceivers. Additionally, the Rx will not phase invert (erroneously change state), even with CMVs of ±40V or differential voltages as large as 40V. High VOD Improves Noise Immunity and Flexibility The ISL3249xE driver design delivers larger differential output voltages (VOD) than the RS-485 standard requires or than most RS-485 transmitters can deliver. The typical ±2.5V VOD provides more noise immunity than networks built using many other transceivers. Another advantage of the large VOD is the ability to drive more than two bus terminations, which allows for utilizing the ISL3249xE in “star” and other multi-terminated, nonstandard network topologies. Figure 10 on page 14 details the transmitter’s VOD vs IOUT characteristic and includes load lines for four (30Ω) and six (20Ω) 120Ω terminations. Figure 10 shows that the driver typically delivers ±1.3V into six terminations, and the “Electrical Specifications” on page 5 guarantees a VOD of ±0.8V at 21Ω over the full temperature range. The RS-485 standard requires a minimum 1.5V VOD into two terminations, but the ISL3249xE deliver RS-485 voltage levels with 2x to 3x the number of terminations. Driver (Tx) Features The RS-485/RS-422 driver is a differential output device that delivers at least 1.5V across a 54Ω load (RS-485) and at least 2.4V across a 100Ω load (RS-422). The drivers feature low propagation delay skew to maximize bit width and minimize EMI, and all drivers are three-statable via the active high DE input. The 250kbps and 1Mbps driver outputs are slew rate limited to minimize EMI and to minimize reflections in unterminated or improperly terminated networks. Outputs of the ISL32496E and ISL32498E drivers are not limited; thus, faster output transition times allow data rates of at least 15Mbps. Hot Plug Function When a piece of equipment powers up, there is a period of time during which the processor or ASIC driving the RS-485 control lines (DE, RE) is unable to ensure that the RS-485 Tx and Rx outputs are kept disabled. If the equipment is connected to the bus, a driver activating prematurely during power-up may crash the bus. To avoid this scenario, the ISL3249xE devices incorporate a “Hot Plug” function. Circuitry monitoring VCC ensures that, during power-up and power-down, the Tx and Rx outputs remain disabled, regardless of the state of DE and RE, if VCC is less High Overvoltage (Fault) Protection Increases Ruggedness NOTE: The available smaller pitch package (MSOP) may not meet the creepage and clearance (C&C) requirements for ±60V levels. The user is advised to determine his C&C requirements before selecting a package type. The ±60V (referenced to the IC GND) fault protection on the RS-485 pins makes these transceivers some of the most rugged 12 FN7786.0 January 18, 2011 ISL32490E, ISL32492E, ISL32493E, ISL32495E, ISL32496E, ISL32498E than ≈3.5V. This gives the processor/ASIC a chance to stabilize and drive the RS-485 control lines to the proper states. Figure 9 illustrates the power-up and power-down performance of the ISL3249xE compared to an RS-485 IC without the Hot Plug feature.

Twisted pair cables tend to pick up noise and other electromagnetically induced voltages as common mode signals, which are effectively rejected by the differential receivers in these ICs. Proper termination is imperative, when using the 15Mbps devices, to minimize reflections. Short networks using the 250kbps versions need not be terminated; however, terminations are recommended unless power dissipation is an overriding concern. In point-to-point or point-to-multipoint (single driver on bus, like RS-422) networks, the main cable should be terminated in its characteristic impedance (typically 120Ω) at the end farthest from the driver. In multi-receiver applications, stubs connecting receivers to the main cable should be kept as short as possible. Multipoint (multi-driver) systems require that the main cable be terminated in its characteristic impedance at both ends. Stubs connecting a transceiver to the main cable should be kept as short as possible. TIME (40µs/DIV) FIGURE 9. HOT PLUG PERFORMANCE (ISL3249xE) vs ISL83088E WITHOUT HOT PLUG CIRCUITRY Built-In Driver Overload Protection As stated previously, the RS-485 specification requires that drivers survive worst-case bus contentions undamaged. These transceivers meet this requirement via driver output short circuit current limits and on-chip thermal shutdown circuitry. The driver output stages incorporate a double foldback, short circuit current limiting scheme, which ensures that the output current never exceeds the RS-485 specification, even at the common mode and fault condition voltage range extremes. The first foldback current level (≈70mA) is set to ensure that the driver never folds back when driving loads with common mode voltages up to ±25V. The very low second foldback current setting (≈9mA) minimizes power dissipation if the Tx is enabled when a fault occurs. In the event of a major short circuit condition, devices also include a thermal shutdown feature that disables the drivers whenever the die temperature becomes excessive. This eliminates the power dissipation, allowing the die to cool. The drivers automatically re-enable after the die temperature drops about +15°C. If the contention persists, the thermal shutdown/re-enable cycle repeats until the fault is cleared. Receivers stay operational during thermal shutdown. ESD Protection All pins on these devices include class 3 (>8kV) Human Body Model (HBM) ESD protection structures that are good enough to survive ESD events commonly seen during manufacturing. Even so, the RS-485 pins (driver outputs and receiver inputs) incorporate more advanced structures, allowing them to survive ESD events in excess of ±16.5kV HBM (±15kV for full-duplex version). The RS-485 pins are particularly vulnerable to ESD strikes because they typically connect to an exposed port on the exterior of the finished product. Simply touching the port pins or connecting a cable can cause an ESD event that might destroy unprotected ICs. These new ESD structures protect the device whether or not it is powered up, and without interfering with the exceptional ±25V CMR. This built-in ESD protection minimizes the need for board-level protection structures (e.g., transient suppression diodes) and the associated, undesirable capacitive load they present. Data Rate, Cables, and Terminations RS-485/RS-422 are intended for network lengths up to 4000 feet, but the maximum system data rate decreases as the transmission length increases. Devices operating at 15Mbps may be used at lengths up to 150 feet (46m), but the distance can be increased to 328 feet (100m) by operating at 10Mbps. The 1Mbps versions can operate at full data rates with lengths up to 800 feet (244m). Jitter is the limiting parameter at these faster data rates, so employing encoded data streams (e.g., Manchester coded or Return-to-Zero) may allow increased transmission distances. The slow versions can operate at 115kbps or less at the full 4000-foot (1220m) distance or at 250kbps for lengths up to 3000 feet (915m). DC cable attenuation is the limiting parameter, so using better quality cables (e.g., 22 AWG) may allow increased transmission distance. Low Power Shutdown Mode These BiCMOS transceivers all use a fraction of the power required by competitive devices, but they also include a shutdown feature that reduces the already low quiescent ICC to a 10µA trickle. These devices enter shutdown whenever the receiver and driver are simultaneously disabled (RE = VCC and DE = GND) for a period of at least 600ns. Disabling both the driver and the receiver for less than 60ns guarantees that the transceiver will not enter shutdown. Note that receiver and driver enable times increase when the transceiver enables from shutdown.
