General Description
The MAX1508 is an intelligent, stand-alone constant-current, constant-voltage (CCCV), thermally regulated linear
charger for a single-cell lithium-ion (Li+) battery. The
MAX1508 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 MAX1508 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 to +100°C when fast charging or while
exposed to high ambient temperatures, allowing maximum charging current without damaging the IC.
The MAX1508 achieves high flexibility by providing an
adjustable fast-charge current by an external resistor.
Other features include the charging status (CHG) of the
battery, an active-low control input (EN), and an activelow-input power-source detection output (ACOK).
The MAX1508 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
MAX1508 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.

Pin Description
Detailed Description
The MAX1508 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 MAX1508 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 soft-starts before it
enters the fast-charge stage. The fast-charge 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 MAX1508 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 +100°C, the MAX1508
reduces the charging current so the die temperature
does not exceed the temperature-regulation set point.
The thermal-regulation loop limits the MAX1508 die
temperature to +100°C by reducing the charge current
as necessary (see the Thermal Regulation section).
This feature not only protects the MAX1508 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.
ACOK
Output
Active-Low Output. The open-drain ACOK output
asserts low when +4.25V < VIN< +7V and VIN- V
BATT
> 40mV. ACOK requires an external 100kΩ pullup
resistor to the system’s logic I/O voltage. ACOK is high
impedance in shutdown.
VL Internal Voltage Regulator
The MAX1508 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.

is high. Connect a pullup resistor to the µP’s I/O voltage when interfacing with a µP logic input.

internally connected to GND.

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 MAX1508 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
The MAX1508 features a proprietary thermal-regulation
circuit to protect both the IC and the system from
excessive heat. When the MAX1508’s die temperature
reaches +100°C, the charge current is reduced to prevent any additional increase in the die temperature. An
active thermal loop does not indicate a fault condition.
Thermal regulation allows the MAX1508 to provide continuous charge to the battery under adverse conditions
without causing excessive power dissipation.

Table 1. CHG States
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 MAX1508 is in a thermally enhanced thin DFN package with exposed paddle. Connect the exposed paddle
of the MAX1508 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 MAX1508 to charge the battery with
maximum current, while minimizing the increase in die
temperature.
DC Input Sources
The MAX1508 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 MAX1508 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 MAX1508 provides a complete Li+ charging solution. The Typical Operating Circuit on the front page
shows the MAX1508 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 MAX1508 as a µP-cooperated Li+
battery charger. The MAX1508 starts charging the battery when EN is low. The µP can drive EN high to disable the charger. The MAX1508’s ACOK output
indicates the presence of a valid AC adapter to the µP.
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 MAX1508 can be configured to
charge its battery at the highest current possible from
the host port. Figure 4 shows the MAX1508 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.
