General Description
The MAX3250 is a 3.0V to 5.5V powered, ±50V isolated
EIA/TIA-232 and V.28/V.24 communications interface
with high data-rate capabilities. The MAX3250 is a dual
die part that operates with up to ±50V difference
between the RS-232 side and the logic side (ISOCOM
to GND). This makes the device ideal for operation in
noisy conditions with high common-mode voltages.
This feature prevents damage to the device if RS-232
lines are inadvertently short-circuited to a +24V or ±48V
power bus.
The MAX3250 is powered by a single 3V to 5.5V supply
on the logic side. Power is transferred from the logic
side to the isolated side by ±100V external capacitors.
The MAX3250 has two receivers (Rx) and two drivers
(Tx) and is guaranteed to run at data rates of 250kbps
while maintaining RS-232 output levels. The transceivers have a proprietary low-dropout transmitter output stage, delivering true RS-232 performance from a
3V to 5.5V supply with a dual charge pump. The device
features a FAULT open-drain output to signal an excessive isolated-side voltage condition on any of the RS232 inputs. This output can drive an alarm LED or can
be monitored by the processor to prevent operation
under these conditions. The receiver outputs are high
impedance in shutdown, allowing multiple interfaces
(IrDA, RS-232, RS-485) to be connected to the same
UART.
The MAX3250 is available in a space-saving 28-pin
SSOP package.

Detailed Description
The MAX3250 is a 3.0V to 5.5V powered, ±50V isolated
EIA/TIA-232 and V.28/V.24 communications interface
with high data-rate capabilities. The MAX3250 is a dual
die part that operates with up to ±50V difference
between the RS-232 side and the logic side (ISOCOM
to GND). This makes the device ideal for operation in
noisy conditions with high common-mode voltages.
This feature prevents damage to the device if RS-232
lines are inadvertently short-circuited to a +24V or ±48V
power bus.
The MAX3250 typically draws 15mA of supply current
when unloaded. Supply current drops to 20µA when
the device is placed in shutdown mode.
The MAX3250 has two receivers and two drivers and is
guaranteed to operate at data rates up to 250kbps. The
device features a FAULT open-drain output to signal an
excessive isolated-side voltage condition on any of the
RS-232 inputs. This output can drive an alarm LED or can
be monitored by the processor to prevent operation
under these conditions. The receiver outputs are high
impedance in shutdown, allowing multiple interfaces
(IrDA, RS-232, RS-485) to be connected to the same
UART (Figure 1). The MAX3250 is a low-cost replacement
for opto-isolated transceivers.
Isolated Power Supply
The MAX3250 drives a high-frequency square wave into
C1 and a complementary square wave into C2. These

AC waveforms are rectified on the isolated side of the
dual die to power its internal circuitry (ISOV
CC
).
Capacitor C6 filters the output of the rectifier. See the
Typical Operating Circuit.
The power controller works in a dual power mode. Power
is maximum when the isolated power supply is below its
regulation point. Power is reduced when the isolated
power supply is above its regulation point.
Dual Charge-Pump Voltage Converter
The RS-232 drivers are powered from a regulated dual
charge pump that provides output voltages of +5.5V (doubling charge pump) and -5.5V (inverting charge pump)
relative to ISOCOM over the 3.0V to 5.5V VCCrange.
The charge pumps are powered from ISOVCCand
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 (C3, C4) and a reservoir capacitor (C7, C8)
to generate the V+ and V- supplies.
RS-232 Transmitters
The transmitters are inverting level translators that convert
TTL/CMOS-logic levels to ±5.0V EIA/TIA-232-compliant
levels. They guarantee a 250kbps data rate with worstcase loads of 3kΩ in parallel with 1000pF to ISOCOM. In
shutdown, the transmitters are disabled and the outputs
are forced into a high-impedance state. When powered
off or shut down, the outputs can be driven up to ±12V
relative to ISOCOM. The transmitter inputs do not have
pullup resistors. All unused inputs should be connected
to VCCor GND.
RS-232 Receivers
The receivers convert RS-232 signals to CMOS-logic
output levels. The receivers’ outputs are forced into a
high-impedance state when the device is in shutdown.
This allows a single UART to multiplex between different protocols.
Low-Power Shutdown Mode
Shutdown mode is obtained by driving SHDN low. In
shutdown, the devices typically draw only 20µA of supply current and no power is transferred across the isolation capacitors. The charge pumps are disabled, and
the receiver outputs and transmitter outputs are high
impedance. When exiting shutdown the charge pumps
and transmitter outputs are fully operational in typically
500µs (Figure 3). Connect SHDN to V
CC
if the shut-
down mode is not used.
Applications Information
Power Isolation Capacitors
The values for capacitors C1 and C2 are important for
proper operation of the device. These capacitors
should be 0.047µF for 4.5V to 5.5V operation, and
0.47µF for 3.0V to 3.6V operation. Smaller values result
in insufficient supply voltage on the isolated side.
Larger values are not allowed.
Capacitor C9 provides an AC feedback path for proper
controller operation. Connect C9 from ISOCOM to GND.
The values for C1, C2, and C9 determine the maximum
frequency and amplitude of the voltage difference
between the local and isolated ground. Table 1 shows
proper capacitance values.

To achieve full isolation capability, C1, C2, and C9
should be rated for 100V or higher operation and be X7R
or X5R type or metalized film dielectric. Y5V and Z5U
dielectrics should be avoided as their voltage and temperature coefficients make their power-transfer capabilities insufficient.
Charge-Pump and Bypass Capacitors
Capacitors C3–C8 should be X7R or X5R type dielectric. Their voltage rating needs to be 10V or higher.
Layout Information
Because the MAX3250 is intended for systems requiring ±50V isolation, some consideration in component
placement is necessary.
A 20mil air gap should isolate the logic side and the
isolated RS-232 side, across the N.C. pins (pin numbers 6, 7, 22, and 23) of the MAX3250. The only components that cross this air gap should be C1, C2, and
C9, which should all have a minimum 100V rating.
All capacitors should be located as close to the
MAX3250 as possible.
Maximum Voltage Between
ISOCOM and Logic GND
High values of applied isolation voltage and frequency
can cause ripple on ISOVCC, V+, V-, and in extreme
cases on VCC. Therefore, it is recommended that the
isolation-voltage and frequency be limited to the values
shown in the Typical Operating Characteristics.
Insert a 1kΩ 1/4W resistor in series with any isolation
test voltage when testing for maximum values of
applied isolation voltage. Exceeding the maximum limits of voltage and frequency (see the Typical Operating
Characteristics) could trigger a holding current in the
internal ESD-protection device if the ±80V isolation limit
is exceeded. This resistor should not be used in normal
application.
Transmitter Outputs when
Exiting Shutdown
Figure 3 shows two transmitter outputs when exiting
shutdown mode. As they become active, the two transmitter outputs are shown going to opposite RS-232 levels (one transmitter input is high, the other is low). Each
transmitter is loaded with 3kΩ in parallel with 2500pF.
The transmitter outputs display no ringing or undesirable transients as they come out of shutdown. Note that
the transmitters are enabled only when the magnitude
of V- exceeds approximately -3V.
