General Description
The MAX4838–MAX4842 are overvoltage protection ICs
that protect low-voltage systems against voltages of up
to 28V. If the input voltage exceeds the overvoltage trip
level, the MAX4838–MAX4842 turn off the low-cost
external n-channel FET(s) to prevent damage to the
protected components. An internal charge pump elimi-
nates the need for external capacitors and drives the
FET gate for a simple, robust solution.
The MAX4838/MAX4839 have a 7.4V overvoltage
threshold, and the MAX4840/MAX4841 have a 5.8V
overvoltage threshold. The MAX4842 has a 4.7V over-
voltage threshold. The MAX4838–MAX4841 have an
undervoltage lockout (UVLO) threshold of 3.25V while
the MAX4842 has a UVLO of 3.0V. In addition to the
single FET configuration, the devices can be config-
ured with back-to-back external FETs to prevent cur-
rents from being back-driven into the adapter.
On power-up, the device waits for 50ms before driving
GATE high. FLAG is held low for an additional 50ms
after GATE goes high before deasserting. The
MAX4838/MAX4840/MAX4842 have an open-drain
FLAG output, and the MAX4839/MAX4841 have a push-
pull FLAG output. The FLAG output asserts immediately
to an overvoltage fault.
Additional features include a 15kV ESD-protected input
(when bypassed with a 1µF capacitor) and a shutdown
pin (EN) to turn off the device (MAX4838/MAX4840/
MAX4842).
All devices are offered in a small 6-pin SC70 package
and are specified for operation from -40°C to +85°C.

Detailed Description
The MAX4838–MAX4842 provide up to 28V overvoltage
protection for low-voltage systems. When the input volt-
age exceeds the overvoltage trip level, the MAX4838–
MAX4842 turn off a low-cost external n-channel FET(s)
to prevent damage to the protected components. An
internal charge pump (Figure 5) drives the FET gate for
a simple, robust solution.
Undervoltage Lockout (UVLO)
The MAX4838–MAX4841 have a fixed 3.25V typical
undervoltage lockout level (UVLO) while the MAX4842
has a 3.0V typical UVLO. When VIN is less than the
UVLO, the GATE driver is held low and FLAG is asserted.
Overvoltage Lockout (OVLO)
The MAX4838/MAX4839 have a 7.4V typical overvoltage
threshold (OVLO), and the MAX4840/MAX4841 have a
5.8V typical overvoltage threshold. The MAX4842 has a
4.7V typical overvoltage threshold. When VIN is greater
than OVLO, the GATE driver is held low and FLAG is
asserted.
FLAG
Output
The FLAG output is used to signal the host system
there is a fault with the input voltage. FLAG asserts
immediately to an overvoltage fault. FLAG is held low
for 50ms after GATE turns on before deasserting.
The MAX4839 and MAX4841 have a push-pull FLAG out-
put. The output high voltage is proportional to VIN for VIN
up to 5.5V, and fixed at 5.5V when VIN > 5.5V.
The MAX4838/MAX4840/MAX4842 have an open-drain
FLAG output. Connect a pullup resistor from FLAG to
the logic I/O voltage of the host system.
EN
Enable Input
EN is an active-low enable input on the MAX4838/
MAX4840/MAX4842 only. Drive EN low or connect to
ground to enable normal device operation. Drive EN
high to force the external MOSFET(s) off. EN does not
override an OVLO or UVLO fault.
GATE Driver
An on-chip charge pump is used to drive GATE above
IN, allowing the use of low-cost n-channel MOSFETS.
The charge pump operates from the internal 5.5V
regulator.
The actual GATE output voltage tracks approximately
two times VIN until VIN exceeds 5.5V or the OVLO trip
level is exceeded, whichever comes first. The
MAX4838/MAX4839 have a 7.4V typical OVLO, there-
fore GATE remains relatively constant at about 10.5V
for 5.5V < VIN < 7.4V. The MAX4840/MAX4841 have a
5.8V typical OVLO, but this can be as low as 5.5V. The
MAX4840/MAX4841 in practice may never actually
achieve the full 10.5V GATE output. The MAX4842 has
a 4.7V (typ) OVLO and the GATE output voltage is 2x
the input voltage. The GATE output voltage as a func-
tion of input voltage is shown in the Typical Operating
Characteristics.
Device Operation
The MAX4838–MAX4842 have an on-board state
machine to control device operation. A flowchart is
shown in Figure 6. On initial power-up, if VIN < UVLO or
if VIN > OVLO, GATE is held at 0V, and FLAG is low.
If UVLO < VIN < OVLO and EN is low, the device enters
startup after a 50ms internal delay. The internal charge
pump is enabled, and GATE begins to be driven above
VIN by the internal charge pump. FLAG is held low dur-
ing startup until the FLAG blanking period expires, typi-

point the device is in its on state.
At any time if VIN drops below UVLO, FLAG is driven

Applications Information
MOSFET Configuration
The MAX4838–MAX4842 can be used with either a sin-
gle MOSFET configuration as shown in the Typical
Operating Circuit, or can be configured with a back-to-
back MOSFET as shown in Figure 7.
The MAX4838–MAX4842 can drive either a single
MOSFET or back-to-back MOSFETs. The back-to-back
configuration has almost zero reverse current when the
input supply is below the output.
If reverse current leakage is not a concern, a single
MOSFET can be used. This approach has half the loss
of the back-to-back configuration when used with simi-
lar MOSFET types, and is a lower cost solution. Note
that if the input is actually pulled low, the output is
pulled low as well due to the parasitic body diode in the
MOSFET. If this is a concern, then the back-to-back
configuration should be used.
MOSFET Selection
The MAX4838–MAX4842 are designed for use with
either a single n-channel MOSFET or dual back-to-back
n-channel MOSFETs. In most situations, MOSFETs with
RDS(ON) specified for a VGS of 4.5V work well. If the
input supply is near the UVLO maximum of 3.5V con-
sider using a MOSFET specified for a lower VGS volt-
age. Also the VDS should be 30V for the MOSFET to
withstand the full 28V IN range of the MAX4838–
MAX4842. Table 1 shows a selection of MOSFETs
appropriate for use with the MAX4838–MAX4842.
IN Bypass Considerations
For most applications, bypass IN to GND with a 1µF
ceramic capacitor. If the power source has significant
inductance due to long lead length, take care to pre-
vent overshoots due to the LC tank circuit and provide
protection if necessary to prevent exceeding the 30V
absolute maximum rating on IN.
The MAX4838–MAX4842 provide protection against volt-
age faults up to 28V, but this does not include negative
voltages. If negative voltages are a concern, connect a
Schottky diode from IN to GND to clamp negative
input voltages.
ESD Test Conditions
ESD performance depends on a number of conditions.
The MAX4838–MAX4842 are specified for 15kV typical
ESD resistance on IN when IN is bypassed to ground
with a 1µF ceramic capacitor. Contact Maxim for a reli-

Human Body Model
Figure 8 shows the Human Body Model and Figure 9
shows the current waveform it generates when dis-
charged into a low impedance. This model consists of
a 100pF capacitor charged to the ESD voltage of inter-
est, which is then discharged into the device through a
1.5kΩresistor.
IEC 1000-4-2
Since January 1996, all equipment manufactured and/or
sold in the European community has been required to
meet the stringent IEC 1000-4-2 specification. The IEC
1000-4-2 standard covers ESD testing and performance
of finished equipment; it does not specifically refer to
integrated circuits. The MAX4838–MAX4842 help users
design equipment that meets Level 3 of IEC 1000-4-2,
without additional ESD-protection components.
The main difference between tests done using the
Human Body Model and IEC 1000-4-2 is higher peak
current in IEC 1000-4-2. Because series resistance is
lower in the IEC 1000-4-2 ESD test model (Figure 10),
the ESD-withstand voltage measured to this standard is
generally lower than that measured using the Human
Body Model. Figure 11 shows the current waveform for
the ±8kV IEC 1000-4-2 Level 4 ESD Contact Discharge
test. The Air-Gap test involves approaching the device
with a charger probe. The Contact Discharge method
connects the probe to the device before the probe is
energized.
