General Description
The MAX4838A/MAX4840A/MAX4842A 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 MAX4838A/MAX4840A/
MAX4842A turn off the low-cost external n-channel
FET(s) to prevent damage to the protected components.
An internal charge pump eliminates the need for external
capacitors and drives the FET gate for a simple,
robust solution.
The MAX4838A has a 7.4V overvoltage threshold, and
the MAX4840A has a 5.8V overvoltage threshold. The
MAX4842A has a 4.7V overvoltage threshold. The
MAX4838A/MAX4840A have an undervoltage-lockout
(UVLO) threshold of 3.25V, while the MAX4842A has a
UVLO of 2.5V. In addition to the single FET configura-
tion, the devices can be configured with back-to-back
external FETs to prevent currents from being back-dri-
ven 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
MAX4838A/MAX4840A/MAX4842A have an open-drain
FLAG output. The FLAG output asserts immediately to
an overvoltage fault.
Additional features include a ±15kV (HBM) ESD-pro-
tected input (when bypassed with a 1µF capacitor) and
a shutdown pin (EN) to turn off the device.
All devices are offered in a small 6-pin SC70 and 6-pin
1.5mm x 1.0mm µDFN packages and are specified
over the -40°C to +85°C extended temperature range.

Detailed Description
The MAX4838A/MAX4840A/MAX4842A provide up to
+28V overvoltage protection for low-voltage systems.
When the input voltage exceeds the overvoltage trip level,
the MAX4838A/MAX4840A/MAX4842A turn off a low-cost
external n-channel FET(s) to prevent damage to the pro-
tected components. An internal charge pump (Figure 5)
drives the FET gate for a simple, robust solution.
Undervoltage Lockout (UVLO)
The MAX4838A/MAX4840A have a fixed 3.25V typical
undervoltage-lockout level (UVLO) while the MAX4842A
has a 2.5V typical UVLO. When VIN is less than the
UVLO, the GATE driver is held low and FLAG is asserted.
Overvoltage Lockout (OVLO)
The MAX4838A has a 7.4V typical overvoltage threshold
(OVLO), and the MAX4840A has a 5.8V typical overvolt-
age threshold. The MAX4842A has a 4.7V typical over-
voltage 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.
All devices 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. Drive EN low or con-
nect 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
MAX4838A has a 7.4V typical OVLO; therefore GATE
remains relatively constant at approximately 10.5V for
5.5V < VIN < 7.4V. The MAX4840A has a 5.8V typical
OVLO, but this can be as low as 5.5V. The MAX4840A
in practice may never actually achieve the full 10.5V
GATE output. The MAX4842A has a 4.7V (typ) OVLO,
and the GATE output voltage is 2x the input voltage.
The GATE output voltage as a function of input voltage
is shown in the Typical Operating Characteristics.
Device Operation
The MAX4838A/MAX4840A/MAX4842A 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-
cally 50ms after the GATE starts going high. At this
point the device is in its on state.
At any time if VIN drops below UVLO, FLAG is driven
low and GATE is driven to ground.

Applications Information
MOSFET Configuration
The MAX4838A/MAX4840A/MAX4842A can be used
with either a single 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
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 MAX4838A/MAX4840A/MAX4842A 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, consider using a MOSFET specified for a lower
VGS voltage. Also, the VDS should be 30V for the MOS-
FET to withstand the full 28V IN range of all devices.
Table 1 shows a selection of MOSFETs appropriate for
use with the MAX4838A/MAX4840A/MAX4842A.
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 MAX4838A/MAX4840A/MAX4842A provide protec-
tion against voltage faults up to 28V, but this does not
include negative voltages. If negative voltages are a con-
cern, 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 MAX4838A/MAX4840A/MAX4842A are specified
for ±15kV typical ESD resistance on IN when IN is
bypassed to ground with a 1µF ceramic capacitor.
Contact Maxim for a reliability report that documents
test setup, methodology, and results.
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
1.5kresistor.

IEC 61000-4-2
Since January 1996, all equipment manufactured and/or
sold in the European community has been required to
meet the stringent IEC 61000-4-2 specification. The IEC
61000-4-2 standard covers ESD testing and perfor-
mance of finished equipment; it does not specifically
refer to integrated circuits. The MAX4838A/MAX4840A/
MAX4842A help users design equipment that meets
Level 3 of IEC 61000-4-2, without additional ESD-protec-
tion components.
The main difference between tests done using the
Human Body Model and IEC 61000-4-2 is higher peak
current in IEC 61000-4-2. Because series resistance is
lower in the IEC 61000-4-2 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 61000-4-2 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.
