data sheet adm3307e/adm3310e/adm3311e/adm3312e/adm3315e rev. i | page 3 of 24 general description the adm33xxe line of driver/receiver products is designed to fully meet the eia-232 standard while operating with a single 2.7 v to 3.6 v power supply. the devices feature an on-board charge pump dc-to-dc converter, eliminating the need for dual power supplies. this dc-to-dc converter contains a voltage tripler and a voltage inverter that internally generates positive and negative supplies from the input 3 v power supply. the dc- to-dc converter operates in green idle mode, whereby the charge pump oscillator is gated on and off to maintain the output voltage at 7.25 v under varying load conditions. this minimizes the power consumption and makes these products ideal for battery-powered portable devices. the adm33xxe devices are suitable for operation in harsh electrical environments and contain esd protection up to 15 kv on their rs-232 lines (adm3310e, adm3311e, adm3312e, and adm3315e). the adm3307e contains esd protection up to 15 kv on all i/o lines (cmos, rs-232, en , and sd). a shutdown facility that reduces the power consumption to 66 nw is also provided. while in shutdown, one receiver remains active (two receivers active with adm3310e), thereby allowing monitor- ing of peripheral devices. this feature allows the device to be shut down until a peripheral device begins communication. the active receiver can alert the processor, which can then take the adm33xxe device out of the shutdown mode. the adm3307e contains five drivers and three receivers and is intended for mobile phone data lump cables and portable computing applications. the adm3311e contains three drivers and five receivers and is intended for serial port applications on notebook/laptop computers. the adm3310e is a low current version of the adm3311e. this device also allows two rece ivers to be active in shutdown mode. the adm3312e contains three drivers and three receivers and is intended for serial port applications, pdas, mobile phone data lump cables, and other hand-held devices. the adm3315e is a low current version of the adm3312e, with a 22 k receiver input resistance that reduces the drive requirements of the dte. its main applications are pdas, palmtop computers, and mobile phone data lump cables. the adm33xxe devices are fabricated using cmos technology for minimal power consumption. all parts feature a high level of overvoltage protection and latch-up immunity. all adm33xxe devices are available in a 32-lead 5 mm 5 mm lfcsp_wq and in a tssop (adm3307e, adm3310e, and adm3311e in a 28-lead tssop; adm3312e and adm3315e in a 24-lead tssop). the adm3311e also comes in a 28-lead ssop. the adm33xxe devices are ruggedized rs-232 line drivers/receivers that operate from a single supply of 2.7 v to 3.6 v. step-up voltage converters coupled with level shifting transmitters and receivers allow rs-232 levels to be developed while operating from a single supply. features include low power consumption, green idle operation, high transmission rates, and compatibility with the eu directive on electromag- netic compatibility. this em compatibility directive includes protection against radiated and conducted interference, including high levels of electrostatic discharge. all rs-232 (and cmos, sd, and en for adm3307e) inputs and outputs are protected against electrostatic discharges (up to 15 kv). this ensures compliance with iec 1000-4-2 requirements. these devices are ideally suited for operation in electrically harsh environments or where rs-232 cables are frequently being plugged/unplugged. they are also immune to high rf field strengths without special shielding precautions. emissions are also controlled to within very strict limits. cmos technology is used to keep the power dissipation to an absolute minimum, allowing maximum battery life in portable applications.

data sheet adm3307e/adm3310e/adm3311e/adm3312e/adm3315e rev. i | page 13 of 24 circuit description the internal circuitry consists mainly of four sections. these include the following: ? a charge pump voltage converter ? 3.3 v logic to eia-232 transmitters ? eia-232 to 3.3 v logic receivers ? transient protection circuit on all i/o lines charge pump dc-to-dc voltage converter the charge pump voltage converter consists of a 250 khz (300 khz for adm3307e) oscillator and a switching matrix. the converter generates a 9 v supply from the input 3.0 v level. this is done in two stages using a switched capacitor technique. first, the 3.0 v input supply is tripled to 9.0 v using capacitor c4 as the charge storage element. the +9.0 v level is then inverted to generate ?9.0 v using c5 as the storage element. however, it should be noted that, unlike other charge pump dc- to-dc converters, the charge pump on the adm3307e does not run open-loop. the output voltage is regulated to 7.25 v (or 6.5 v for the adm3310e and adm3315e) by the green idle circuit and never reaches 9 v in practice. this saves power as well as maintains a more constant output voltage. + gnd c2 c1 s1 s2 s3 s4 c4 v cc s5 s6 s7 + + v+ = 3v cc v cc internal oscillator v cc 02915-024 figure 24. charge pump voltage tripler the tripler operates in two phases. during the oscillator low phase, s1 and s2 are closed and c1 charges rapidly to v cc . s3, s4, and s5 are open, and s6 and s7 are closed. during the oscillator high phase, s1 and s2 are open, and s3 and s4 are closed, so the voltage at the output of s3 is 2v cc . this voltage is used to charge c2. in the absence of any discharge current, c2 charges up to 2v cc after several cycles. during the oscillator high phase, as previously mentioned, s6 and s7 are closed, so the voltage at the output of s6 is 3v cc . this voltage is then used to charge c3. the voltage inverter is illustrated in figure 25. + gnd c3 s8 s9 s10 s11 c5 v? = ?(v+) + gnd v+ internal oscillator from voltage tripler 02915-025 figure 25. charge pump voltage inverter during the oscillator high phase, s10 and s11 are open, while s8 and s9 are closed. c3 is charged to 3v cc from the output of the voltage tripler over several cycles. during the oscillator low phase, s8 and s9 are open, while s10 and s11 are closed. c3 is connected across c5, whose positive terminal is grounded and whose negative terminal is the v? output. over several cycles, c5 charges to ?3 v cc . the v+ and v? supplies may also be used to power external circuitry if the current requirements are small. see figure 12 in the typical performance characteristics section. what is green idle? green idle is a method of minimizing power consumption under idle (no transmit) conditions while still maintaining the ability to transmit data instantly. how does it work? charge pump type dc-to-dc converters used in rs-232 line drivers normally operate open-loop, that is, the output voltage is not regulated in any way. under light load conditions, the output voltage is close to twice the supply voltage for a doubler and three times the supply voltage for a tripler, with very little ripple. as the load current increases, the output voltage falls and the ripple voltage increases. even under no-load conditions, the oscillator and charge pump operate at a very high frequency with consequent switching losses and current drain. green idle works by monitoring the output voltage and maintaining it at a constant value of around 7 v 1 . when the voltage rises above 7.25 v 2 the oscillator is turned off. when the voltage falls below 7 v 1 , the oscillator is turned on and a burst of charging pulses is sent to the reservoir capacitor. when the oscillator is turned off, the power consumption of the charge pump is virtually zero, so the average current drain under light load conditions is greatly reduced. 1 for adm3310e and adm3315e , replace with 6.5 v. 2 for adm3310e and adm3315e , replace with 6.25 v.
