MAXIM MAX3221 MAX3223 MAX3243 说明书

_______________General DescriptionThe MAX3221/MAX3223/MAX3243 achieve 1µA supply current with Maxim’s revolutionary AutoShutdown™ fea-ture. When the MAX3221/MAX3223/MAX3243 do not sense a valid signal level on their receiver inputs, the on-board power supply and drivers shut down. This occurs if the RS-232 cable is disconnected or if the transmitters of the connected peripheral are turned off.The system turns on again when a valid level is applied to any RS-232 receiver input. As a result, the system saves power without changes to the existing BIOS or operating system.The MAX3221/MAX3223/MAX3243 transceivers are 3V-powered EIA/TIA-232 and V.28/V.24 communications interfaces intended for notebook computer applica-tions. A proprietary, high-efficiency, dual charge-pump power supply and a low-dropout transmitter combine to deliver true RS-232 performance from a single +3.0V to +5.5V supply. A guaranteed data rate of 120kbps pro-vides compatibility with popular software for communi-cating with personal computers.The MAX3221/MAX3223/MAX3243 require only 0.1µF capacitors in 3.3V operation, and can operate from input voltages ranging from +3.0V to +5.5V. They are ideal for 3.3V-only systems, mixed 3.3V and 5.0V systems, or 5.0V-only systems that require true RS-232 performance.The MAX3221 is a 1-driver/1-receiver 16-pin SSOP ver-sion of the 20-pin MAX3223 (2-driver/2-receiver). The MAX3243 3-driver/5-receiver, complete serial port is ideal for notebook or subnotebook computers. The MAX3243 includes one complementary always-active receiver. This receiver can monitor an external device (such as a modem) in shutdown, without forward bias-ing the protection diodes in a UART that may have V CC completely removed.Next Generation Device Features♦For Space-Constrained Applications:MAX3228/MAX3229: +2.5V to +5.5V RS-232Transceivers in UCSP™♦For Integrated ESD Protection:MAX3222E/MAX3232E/MAX3237E/MAX3241E*/MAX3246E: ±15kV ESD-Protected, Down to 10nA,3.0V to 5.5V, Up to 1Mbps, True RS-232Transceivers (MAX3246E Available in UCSP Package)♦For Low-Voltage or Data Cable Applications:MAX3380E/MAX3381E: +2.5V to +5.5V, 1µA, 2 Tx/2 Rx RS-232 Transceivers with ±15kV ESD-Protected I/O and Logic Pins________________________ApplicationsNotebook, Subnotebook, and Palmtop Computers Battery-Powered Equipment Hand-Held Equipment Peripherals PrintersMAX3221/MAX3223/MAX3243*1µA Supply-Current, True +3V to +5.5V RS-232 Transceivers with AutoShutdown________________________________________________________________Maxim Integrated Products119-0306; Rev 8; 10/03* Covered by U.S. Patent numbers 4,636,930; 4,679,134; 4,777,577; 4,797,899; 4,809,152; 4,897,774; 4,999,761; and other patents pending.†Future product—contact factory for availability.AutoShutdown and UCSP are trademarks of Maxim Integrated Products, Inc.Pin Configurations appear at end of data sheet.Typical Operating Circuits appear at end of data sheet._____________________Selector GuideFor pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .M A X 3221/M A X 3223/M A X 32431µA Supply-Current, True +3V to +5.5V RS-232 Transceivers with AutoShutdown 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICS(V CC = +3.0V to +5.5V, C1–C4 = 0.1µF (Note 2), T A = T MIN to T MAX , unless otherwise noted.

The charge pumps operate in a discontinuous mode: if the output voltages are less than 5.5V, the charge pumps are enabled; if the output voltages exceed 5.5V, the charge pumps are disabled. Each charge pump requires a flying capacitor (C1, C2) and a reservoir capacitor (C3, C4) to generate the V+ and V- supplies.RS-232 TransmittersThe transmitters are inverting level translators that con-vert CMOS-logic levels to 5.0V EIA/TIA-232 levels. They guarantee a 120kbps data rate with worst-case loads of 3k Ωin parallel with 1000pF, providing compatibility with PC-to-PC communication software (such as Laplink™).Typically, the MAX3221/MAX3223/MAX3243 can oper-ate at data rates of 235kbps. Transmitters can be paral-leled to drive multiple receivers or mice (MAX3243).Figure 1 shows a complete system connection.When FORCEOFF is driven to ground, or the Auto-Shutdown circuitry senses invalid voltage levels at all receiver inputs, the transmitters are disabled and the outputs are forced into a high-impedance state.M A X 3221/M A X 3223/M A X 32431µA Supply-Current, True +3V to +5.5V RS-232 Transceivers with AutoShutdown 6_______________________________________________________________________________________RS-232 ReceiversThe MAX3221/MAX3223/MAX3243’s receivers convert RS-232 signals to CMOS-logic output levels. All receivers have one inverting three-state output. In shut-down (FORCEOFF = low) or in AutoShutdown, the MAX3221/MAX3223’s receivers are active (Table 1).Driving EN high places the receiver(s) in a high-imped-ance state. The MAX3243’s receivers are high imped-ance when the part is shut down.The MAX3243 has an always-active complementary output (R2OUTB). R2OUTB is an extra output that mon-itors receiver activity while the other receivers are high impedance. This allows Ring Indicator to be monitored without forward biasing other devices connected to the receiver outputs. This is ideal for systems where V CC is set to 0V in shutdown to accommodate peripherals,such as UARTs (Figure 2).Figure 1. Interface Under Control of PMUFigure 2. The MAX3243 detects RS-232 activity when the UART and interface are shut down.MAX3221/MAX3223/MAX32431µA Supply-Current, True +3V to +5.5V RS-232 Transceivers with AutoShutdown_______________________________________________________________________________________7AutoShutdownA 1µA supply current is achieved with Maxim’s new AutoShutdown feature, which operates when FORCEON is low and FORCEOFF is high. When the MAX3221/MAX3223/MAX3243 sense no valid signal levels on all receiver inputs for 30µs, the on-board power supply and drivers are shut off, reducing supply current to 1µA. This occurs if the RS-232 cable is dis-connected or the connected peripheral transmitters are turned off. The system turns on again when a valid level is applied to any RS-232 receiver input. As a result, the system saves power without changes to the existing BIOS or operating system. When using AutoShutdown,the INVALID output is high when the device is on and low when the device is shut down. Because I NVALID indicates the receiver inputs’ condition, it can be used in any mode (Figure 3).Table 2 and Figure 3c summarize the MAX3221/MAX3223/MAX3243operating modes. FORCEON and FORCEOFF override the automatic circuitry and force the transceiver into its normal operating state or into its low-power standby state. When neither control is assert-ed, the IC selects between these states automatically based on receiver input levels. Figures 3a, 3b, and 5a depict valid and invalid RS-232 receiver levels.A mouse or other system with AutoShutdown may need time to wake up. Figure 4 shows a circuit that forces the transmitters on for 100ms, allowing enough time for theFigure 3a. MAX32_ _ Entering 1µA Supply Mode via AutoShutdown*Note:If the part is in AutoShutdown mode (FORCEOFF = V CC ,FORCEON = GND), it is shut down if no valid RS-232levels are present on all receiver inputs.Figure 4.

If the other system outputs valid RS-232 signals within that time, the RS-232 ports on both systems remain enabled.When shut down, the device’s charge pumps are turned off, V+ decays to V CC , V- decays to ground, and the transmitter outputs are disabled (high impedance). The time required to exit shutdown is typically 100µs (Figure 5b).Software-Controlled ShutdownIf direct software control is desired, INVALID can be used to indicate DTR or Ring Indicator signal. Tie FORCEOFF and FORCEON together to bypass Auto-Shutdown so the line acts like a SHDN input.___________Applications InformationCapacitor SelectionThe capacitor type used for C1–C4 is not critical for proper operation; either polarized or nonpolarized capacitors may be used. The charge pump requires 0.1µF capacitors for 3.3V operation. For other supply voltages, refer to Table 3 for required capacitor values.Do not use values smaller than those listed in Table 3.Increasing the capacitor values (e.g., by a factor of 2)reduces ripple on the transmitter outputs and slightly reduces power consumption. C2, C3, and C4 can be increased without changing C1’s value. However, do not increase C1 without also increasing the values of C2, C3, and C4 to maintain the proper ratios (C1to the other capacitors).When using the minimum required capacitor values,make sure the capacitor value does not degrade excessively with temperature. If in doubt, use capaci-tors with a larger nominal value. The capacitor’s equiva-lent series resistance (ESR) usually rises at low temperatures and influences the amount of ripple on V+ and V-.Table 2.

In applications that are sensitive to power-supply noise, decouple V CC to ground with a capacitor of the same value as the charge-pump capacitor C1.Connect bypass capacitors as close to the IC as possible.Transmitter Outputs when Exiting ShutdownFigure 6 shows two transmitter outputs when exiting shutdown mode. As they become active, the two trans-mitter outputs are shown going to opposite RS-232levels. Each transmitter is loaded with 3k Ωin parallel with 2500pF. The transmitter outputs display no ringing or undesirable transients as they come out of shut-down. Note that the transmitters are enabled only when the magnitude of V- exceeds approximately 3V. Figure 7a shows the MAX3243’s transmitter output voltage vs. current per transmitter. Figure 7b is a mouse driver test circuit.Mouse Driveability (MAX3243)The MAX3243 has been specifically designed to power serial mice while operating from low-voltage power sup-plies. It has been tested with samples of ten major mouse models from six manufacturers including the leading three: Logitech (5 models), Mouse Systems, andMicrosoft. The MAX3243 successfully drove all serial mice and met their respective current and voltage requirements. Figure 7a shows the transmitter outputs under increasing load current. The MAX3243’s switching regulator ensures the transmitters will supply at least ±5V during worst-case conditions. The AutoShutdown feature does not work with a mouse, so FORCEOFF and FORCEON should be connected to V CC .High Data RatesThe MAX3221/MAX3223/MAX3243 maintain the RS-232±5.0V minimum transmitter output voltage even at high data rates. Figure 8 shows a transmitter loopback test circuit. Figure 9 shows a loopback test result at 120kbps, and Figure 10 shows the same test at 235kbps. For Figure 9, all three transmitters were driv-en simultaneously at 120kbps into RS-232 loads in par-allel with 1000pF. For Figure 10, a single transmitter was driven at 235kbps, but all three transmitters were loaded with an RS-232 receiver in parallel with 1000pF.Interconnection with 3V and 5V LogicThe MAX3221/MAX3223/MAX3243 can directly inter-face with various 5V logic families, including ACT and HCT CMOS. See Table 4 for more information on possi-ble combinations of interconnections.Figure 7a.
