General Description
The MAX4880 is an overvoltage-protection controller
with an internal current-limited switch that can be configured as a low-cost battery charger. When the input
voltage exceeds the overvoltage trip level (5.7V), or
drops below the undervoltage-lockout level (4.2V), the
MAX4880 turns off the external n-channel MOSFET and
asserts an undervoltage/overvoltage flag indicator
(FLAGV) low to notify the processor.
The MAX4880 internal current-limited switch limits the
charge current flowing to the battery to 525mA. The
switch opens when the battery voltage reaches its fullcharged state (4.2V), and a flag (BAT_OK) asserts to
notify the processor. The MAX4880 includes a switchcontrol input (CB) to turn off the internal current-limited
switch, regardless of the battery voltage.
The MAX4880 also features a built-in startup delay that
allows the adapter voltage to settle down before turning
on the MOSFET. Other features include 15kV ESD protection for the input and a shutdown function (EN) to
turn off the external n-channel MOSFET.
The MAX4880 is available in a space-saving 10-pin
TDFN package and is specified for operation over the
extended -40°C to +85°C temperature range.

Detailed Description
The MAX4880 provides up to 28V overvoltage protection
for low-voltage systems. When the input voltage at IN
exceeds the overvoltage trip level (OVLO), the MAX4880
turns off a low-cost, external n-channel MOSFET to prevent damage to the protected components and issues
an overvoltage fault flag.
When the correct adapter is plugged in, the n-channel
MOSFET is turned on. The output of the MOSFET is
then connected to the internal current-limit switch that
provides the charge-current path to the battery. When
the battery reaches the trip voltage (4.2V), the internal
switch turns off and BAT_OK asserts low, indicating
that the battery has reached its full charged state. The
internal switch turns back on only when the battery voltage drops by more than 200mV.
IN Overvoltage Lockout (OVLO)
The MAX4880 has a 5.6V typical overvoltage threshold
(OVLO). When VINis higher than V
OVLO
, GATE goes
low to turn off the external n-channel MOSFET. An overvoltage FLAGV is asserted low to notify the processor
of the fault condition.
IN Undervoltage Lockout (UVLO)
The MAX4880 includes a fixed 4.35V typical undervoltage-lockout level (UVLO). When VINis below the V
UVLO
(1.2V ≤ VIN≤ 4.35V), GATE goes low to turn off the
external n-channel MOSFET. In addition, the driver for
the internal switch (BTA-BTB) is also turned off; therefore, this switch is open. This ensures the reverse current, drained from the battery, is less than 1µA when
the adapter is not present.
Fault Flag Output (
FLAGV
)
The FLAGV output signals the host system that there is
a fault with the input voltage. FLAGV asserts low in
response to either an overvoltage or an undervoltage
fault. FLAGV stays low for 50ms after GATE turns on,
before deasserting high.
FLAGV is an open-drain, active-low output. Connect a
pullup resistor from FLAGV to the logic I/O voltage of
the host system or to any voltage source up to 6V.
FLAGV is invalid when driving EN high.
Battery-Voltage-Limit Flag Output
(
BAT_OK
)
The MAX4880 includes a battery-voltage-limit flag output (BAT_OK). BAT_OK asserts low to indicate the voltage on BTB exceeds the BTB trip level of 4.2V.
BAT_OK deasserts high when the voltage on BTB falls
by the BTB hysteresis voltage of more than 200mV.
BAT_OK is an open-drain, active-low output. Connect a
pullup resistor from BAT_OK to the logic I/O voltage of
the host system, or to any voltage source up to 6V.
BAT_OK is invalid when driving EN high.
EN
Input
The MAX4880 features an active-low enable input (EN).
Drive EN low or connect to ground for normal operation. Drive EN high to force the external n-channel
MOSFET off, disabling FLAGV and BAT_OK.
Internal Current Limit (BTA to BTB)
The internal switch from BTA to BTB has a preset current-limit of 525mA (typ). If the load current from BTA to
BTB reaches this current limit, the switch operates in
the continuous mode, limiting the load current to the
preset value.
The switch remains in the current-limit condition until the
battery voltage on BTB exceeds 4.2V, or until the control
bit CB is driven low to open the switch.
Internal Switch Control Input (CB)
The CB input controls the internal switch. When CB is
high, the on/off state of the internal switch depends on
the battery voltage level. The internal switch turns off
when the battery voltage reaches the BTB trip level,

and turns back on when the battery falls below the BTB
trip level minus BTB hysteresis. Drive CB low to turn off
the internal switch, regardless of the battery voltage.
This control bit can be used to provide additional topoff charge for the battery. When the CB pin is cycled,
the internal battery switch is turned on and off. This
effectively provides an average current that is lower
than the full-charge current.
GATE Driver
An on-chip charge pump drives the GATE voltage to
approximately twice VIN, allowing the use of a low-cost,
n-channel MOSFET (Figure 5). The actual GATE output
voltage tracks approximately 2 x V
IN,
until VINexceeds
the OVLO trip level, 5.6V (typ). The GATE output voltage, as a function of input voltage, is shown in the
Typical Operating Characteristics.
Applications Information
MOSFET Selection
The MAX4880 is designed for use with an n-channel
MOSFET. MOSFETs with R
DS(ON)
specified for a VGSof
4.5V are ideal. If the input supply is near the UVLO minimum of 4.2V, consider using a MOSFET specified for a
lower VGSvoltage. Also, the VDSshould be 30V for the
MOSFET to withstand the full 28V IN range of the
MAX4880. Table 1 shows a selection of MOSFETs
appropriate for use with the MAX4880.
IN Bypass Considerations
Bypass IN to GND with a 1µF ceramic capacitor to
achieve 15kV ESD-protected input. When the power
source has significant inductance due to long lead
length, take care to prevent overshoots due to the LC

The MAX4880 provides protection against voltage
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.
Exposed Pad
The MAX4880 provides an exposed pad on the bottom
of the package. This pad is internally connected to
GND. For the best thermal conductivity and higher
power dissipation, solder the exposed pad to the
ground plane. Do not use the ground-connected pad
as the only electrical ground connection or ground
return. Use GND (pin 6) as the primary electrical
ground connection.
ESD Test Conditions
ESD performance depends on a number of conditions.
The MAX4880 is specified for 15kV typical ESD resistance on IN when IN is bypassed to ground with a 1µF
low-ESR ceramic capacitor. Contact Maxim for a reliability report that documents test setup, methodology,
and results.
Human Body Model
Figure 6 shows the Human Body Model, and Figure 7
shows the current waveform it generates when discharged into a low impedance. This model consists of
a 100pF capacitor charged to the ESD voltage of interest, which is then discharged into the device through a
1.5kΩ resistor.
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 performance of finished equipment; it does not specifically
refer to integrated circuits. The MAX4880 helps users
design equipment that meets Level 3 of IEC 61000-4-2,
without additional ESD-protection 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 8),
the ESD-withstand voltage measured to this standard is
generally lower than that measured using the Human
Body Model. Figure 9 shows the current waveform for
the ±8kV IEC 61000-4-2 Level 4 ESD ContactDischarge test. The Air-Gap test involves approaching
the device with a charger probe. The ContactDischarge method connects the probe to the device
before the probe is energized.
