General Description
The MAX1507 is an intelligent, stand-alone constant-current, constant-voltage (CCCV), thermally regulated linear
charger for a single-cell lithium-ion (Li+) battery. The
MAX1507 integrates the current-sense circuit, MOS pass
element, and thermal-regulation circuitry, and also eliminates the reverse-blocking Schottky diode to create the
simplest and smallest charging solution for hand-held
equipment.
The MAX1507 functions as a stand-alone charger to
control the charging sequence from the prequalification
state through fast-charge, top-off charge, and fullcharge indication.
Proprietary thermal-regulation circuitry limits the die
temperature when fast charging or while exposed to
high ambient temperatures, allowing maximum charging current without damaging the IC.
The MAX1507 achieves high flexibility by providing an
adjustable fast-charge current and thermal regulation
setpoints. Other features include the charging status
(CHG) of the battery and an active-low control input (EN).
The MAX1507 accepts a +4.25V to +13V supply, but disables charging when the input voltage exceeds +7V to
protect against unqualified or faulty AC adapters. The
MAX1507 operates over the extended temperature
range (-40°C to +85°C) and is available in a compact
8-pin thermally enhanced 3mm x 3mm Thin DFN package with 0.8mm height.

MAX1507
Linear Li+ Battery Charger with Integrated Pass FET
and Thermal Regulation in 3mm x 3mm Thin DFN
6 _______________________________________________________________________________________
Detailed Description
The MAX1507 charger uses voltage, current, and thermal-control loops to charge a single Li+ cell and to protect the battery (Figure 1). When a Li+ battery with a
cell voltage below 2.5V is inserted, the MAX1507
charger enters the prequalification stage where it
precharges that cell with 10% of the user-programmed
fast-charge current. The CHG indicator output is driven
low (Figure 2) to indicate entry into the prequalification
state. Once the cell has passed 2.5V, the charger softstarts before it enters the fast-charge stage. The fastcharge current level is programmed through a resistor
from ISET to ground. As the battery voltage approaches 4.2V, the charging current is reduced. If the battery
current drops to less than 10% of the fast-charging current, the CHG indicator goes high impedance, signaling the battery is fully charged. At this point the
MAX1507 enters a constant voltage-regulation mode to

maintain the battery at full charge. If, at any point while
charging the battery, the die temperature approaches
the user-selected temperature setting (TEMP pin), the
MAX1507 reduces the charging current so the die temperature does not exceed the temperature-regulation
set point.
The thermal-regulation loop limits the MAX1507 die
temperature to the value selected by the TEMP input by
reducing the charge current as necessary (see the
Thermal-Regulation Selection section). This feature not
only protects the MAX1507 from overheating, but also
allows higher charge current without risking damage to
the system.
EN
Charger Enable Input
EN is a logic input (active low) to enable the charger.
Drive EN low, leave floating, or connect to GND to
enable the charger control circuitry. Drive EN high to
disable the charger control circuitry. EN has a 200kΩ
internal pulldown resistance.
VL Internal Voltage Regulator
The MAX1507 linear charger contains an internal linear
regulator available on the VL output pin. VL requires a
0.47µF ceramic bypass capacitor to GND. VL is regulated to 3.3V whenever the input voltage is above 3.5V.

Table 1. CHG States
CHG
Charge Indicator Output
CHG is an open-drain current source for indicating
charge status. Table 1 describes the state of CHG during different stages of operation.
CHG is a nominal 12mA current source suitable for driving a charge-indication LED. If the MAX1507 is used
in conjunction with a microprocessor, a pullup resistor
to the logic I/O voltage allows CHG to indicate charge
status to the µP instead of driving an LED.
Soft-Start
An analog soft-start algorithm activates when entering
fast-charge mode. When the prequalification state is
complete (V
BATT
exceeds +2.5V), the charging current
ramps up in 3ms to the full charging current. This
reduces the inrush current on the input supply.
Applications Information
Charge-Current Selection
The maximum charging current is programmed by an
external R
ISET
resistor connected from ISET to GND.
Select the R
ISET
value based on the following formula:
I
FAST
= 1461V / R
ISET
Ω
where I
FAST
is in amps and R
ISET
is in ohms. ISET can
also be used to monitor the fast-charge current level.
The output current from the ISET pin is 0.958mA per
amp of charging current. The output voltage at ISET is
proportional to the charging current as follows:
V
ISET
= (I
CHG
x R
ISET
) / 1044
The voltage at ISET is nominally 1.4V at the selected
fast-charge current, and falls with charging current as
the cell becomes fully charged.
Thermal-Regulation Selection
Set the regulated die temperature of the MAX1507 with
the TEMP three-level logic input. The MAX1507
reduces the charge current to limit the die temperature
to the value set by TEMP. The MAX1507 operates normally while the thermal loop is active. An active thermal
loop does not indicate a fault condition. TEMP allows
the MAX1507 to maximize the charge current while providing protection against excessive power dissipation.
Connect TEMP to GND to regulate the die temperature
at +90°C. Leave TEMP floating to regulate the die temperature at +100°C. Connect TEMP to VL to regulate
the die temperature at +130°C.
Capacitor Selection
Connect a ceramic capacitor from BATT to GND for
proper stability. Use a 1µF X5R ceramic capacitor for
most applications.
Connect a 1µF ceramic capacitor from IN to GND. Use
a larger input bypass capacitor for high input voltages
or high charging currents to reduce supply noise.
Connect a 0.47µF ceramic capacitor from VL to GND.
Thermal Considerations
The MAX1507 is in a thermally enhanced thin DFN
package with exposed paddle. Connect the exposed
paddle of the MAX1507 to a large copper ground plane
to provide a thermal contact between the device and
the circuit board. The exposed paddle transfers heat
away from the device, allowing the MAX1507 to charge
the battery with maximum current, while minimizing the
increase in die temperature.
DC Input Sources
The MAX1507 operates from well-regulated DC
sources. The full-charging input-voltage range is 4.25V
to 7V. The device can stand up to 13V on the input
without damage to the IC. If VINis greater than 7V, then
the MAX1507 stops charging.
An appropriate power supply must provide at least
4.25V when sourcing the desired peak charging current. It also must stay below 6.5V when unloaded.

Application Circuits
Stand-Alone Li+ Charger
The MAX1507 provides a complete Li+ charging solution. The Typical Application Circuit on the front page
shows the MAX1507 as a stand-alone Li+ battery
charger. The 2.8kΩ resistor connected to ISET sets a
charging current of 520mA. The LED indicates when
either fast-charge or precharge qualification has
begun. When the battery is full, the LED turns off.
Microprocessor-Interfaced Charger
Figure 3 shows the MAX1507 as a µP-cooperated Li+
battery charger. The MAX1507 starts charging the battery when EN is low. The µP can drive EN high to disable the charger. Use a logic-biased NPN transistor as
an inverter circuit to generate an AC_ON signal for the
system to detect the presence of an input supply. CHG
can be used to detect the charge status of a battery.
By monitoring V
ISET
, the system can measure the
charge current.
USB-Powered Li+ Charger
The universal serial bus (USB) provides a high-speed
serial communication port as well as power for the
remote device. The MAX1507 can be configured to
charge its battery at the highest current possible from
the host port. Figure 4 shows the MAX1507 as a USB
battery charger. To make the circuit compatible with
either 100mA or 500mA USB ports, the circuit initializes
at 95mA charging current. The microprocessor then
interrogates the host to determine its current capability.
If the host port is capable, the charging current is
increased to 435mA. The 435mA current was chosen to
avoid exceeding the 500mA USB specification.

Layout and Bypassing
Connect a 1µF ceramic input capacitor as close to the
device as possible. Provide a large copper GND plane
to allow the exposed paddle to sink heat away from the
device. Connect the battery to BATT as close to the
device as possible to provide accurate battery voltage
sensing. Make all high-current traces short and wide to
minimize voltage drops. For an example layout, refer to
the MAX1507/MAX1508 evaluation kit layout.
