1 16.5kv esd protected, +125c, 1.8v to 3.6v, low power, sot-23, rs-485/rs-422 transmitters isl32613e, ISL32614E the intersil isl32613e and ISL32614E are 16.5kv hbm esd protected (7kv iec61000 cont act), 1.8v powered, single transmitters for differential communication. these drivers have very low bus currents (40a), so they present less than a ?1/8 unit load? to the bus. this allows more than 256 transmitters on the network, without violating the rs-485 specification?s 32 unit load maximum and without using repeaters. hot plug circuitry ensures that th e tx outputs remain in a high impedance state while the power supply stabilizes. both ics utilize slew rate limite d drivers, which reduce emi and minimize reflections from improp erly terminated transmission lines or unterminated stubs in multidrop and multipoint applications. the isl32613e is more slew rate limited for data rates up to 128kbps, while the less limited ISL32614E is useful for data rates up to 256kbps. for companion low power single rs-485 receivers, please see the isl32610e data sheet. features ? wide supply voltage range . . . . . . . . . . . . . . . . . 1.8v to 3.6v ? low quiescent supply current . . . . . . . . . . . . . . . 80a (max) - very low shutdown supply current . . . . . . . . . . 2a (max) ? high esd protection on rs-485 outputs . . . . 16.5kv hbm - class 3 esd level on all other pins. . . . . . . . . . >8kv hbm ? specified for +125c operation ? hot plug - tx outputs remain three-state during power-up ? low tx leakage allows >256 devices on the bus ? slew rate limited for data rates up to 256kbps ? current limiting and thermal shutdown for driver overload protection ?5v tolerant logic inputs ? pb-free (rohs compliant) applications ? industrial/process control networks ? space-constrained systems ? factory automation ? building environmental control/lighting systems figure 1. v cc 1.8v to 3.6v isl32613e with v cc = 1.8v reduces operating i cc by a factor of 177 compared with i cc at v cc = 3.6v 10 100 1m 10m 1.8 2.0 2.2 2.4 2.6 2.8 3.0 3.2 3.4 3.6 v cc (v) i cc (a) static dynamic (128kbps) r d = , c d = 50pf truth table transmitting inputs outputs de (note 9) di z y 1101 1010 0xhigh-z *high-z * note: *shutdown mode caution: these devices are sensitive to electrostatic discharge; follow proper ic handling procedures. 1-888-intersil or 1-888-468-3774 | copyright intersil americas inc. 2011. all rights reserved intersil (and design) is a trademark owned by intersil corporation or one of its subsidiaries. all other trademarks mentioned are the property of their respective owners. august 30, 2011 fn7906.0

isl32613e, ISL32614E 7 fn7906.0 august 30, 2011 application information driver features these transmitters are differential output devices that operate with v cc as low as 1.8v, and up to 3.6v. devices are rs-485 compliant with v cc 3v, but significant power savings are obtained by operating at v cc = 1.8v. the transmitter outputs are tri-st atable via the active high de input. if the tx enable functi on is not needed, tie de to v cc through a 1k ? to 2k ? resistor. outputs are slew rate limited to minimize emi, and to reduce reflections in unterminated or improperly terminated networks. 1.8v operation the isl32613e and ISL32614E operate with v cc as low as 1.8v. when coupled with the isl32610e or isl32611e 1.8v receivers, they provide a differential commun ication link optimized for very low power, and for slow data rates. figures 7 and 8 illustrate the static and dynamic power savings from using these transmitters at low supply voltages. with v cc = 1.8v rather than 3.3v, using the isl32613e at 128kbps reduces the operating supply current from 9.9ma to 56a (a factor of 177)! 5.5v tolerant logic pins logic input pins (di, de) contain no esd or parasitic diodes to v cc , so they withstand input voltages exceeding 5.5v, regardless of the v cc voltage. 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 line (de) is unable to ensure th at the rs-485 tx outputs are kept disabled. if the equipment is connected to the bus, a driver activating prematurely during po wer-up may crash the bus. to avoid this scenario, these transmitters incorporate a ?hot plug? function. during power-up , circuitry monitoring v cc ensures that the tx outputs remain disabled for a period of time, regardless of the state of de. this gives the processo r/asic a chance to stabilize and drive the control lines to the proper states. esd protection all pins on these devices incl ude class 3 (8kv) human body model (hbm) esd protection stru ctures, but the driver outputs incorporate advanced structures that allow them to survive esd events in excess of 16.5kv hbm and 7kv to the iec61000 contact test method. the rs-485 pins are particularly vulnerable to esd damage 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 unpr otected ics. these new esd structures protect the device whet her it is powered up or not, and without degrading the commo n mode range. this built-in esd protection eliminates the need for board-level protection structures (e.g., transient suppression diodes) and the associated, undesirable capa citive load they present. driver overload protection the driver output stages incorpor ate short-circuit, current-limiting circuitry, which ensures that the output current never exceeds the rs-485 specification over a 2v (-7v to +12v for v cc 2.7v) common mode voltage range. in the event of a major short-circuit condition, the device also includes a thermal sh utdown feature that disables the drivers whenever the die temperature beco mes excessive. this eliminates power dissipation, allowing the die to cool. the drivers automatically re-enable after the die temperature drops by about +20c. if the condition persists, the thermal shutdown/re-enable cycle repeats until the fault is cleared. low power shutdown mode this bicmos transmitter uses a fr action of the power required by its bipolar counterparts, but it also includes a shutdown feature that reduces the already low quiescent i cc to a 10na trickle. this device enters shutdown whenever the driver disables (de = gnd).
