Linear Li+ Battery Charger with Integrated Pass FET,  
Thermal Regulation, and ACOK in 3mm x 3mm TDFN  
General Description  
Features  
The MAX1508 is an intelligent, stand-alone constant-cur-  
rent, 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 elimi-  
nates the reverse-blocking Schottky diode, to create the  
simplest and smallest charging solution for hand-held  
equipment.  
ꢀ Stand-Alone Linear 1-Cell Li+ Battery Charger  
ꢀ No External FET, Reverse-Blocking Diode, or  
Current-Sense Resistor Required  
ꢀ Programmable Fast-Charge Current (0.8A max)  
ꢀ Proprietary Die-Temperature Regulation Control  
(+100°C)  
ꢀ +4.25V to +13V Input Voltage Range with Input  
The MAX1508 functions as a stand-alone charger to  
control the charging sequence from the prequalification  
state through fast-charge, top-off charge, and full-  
charge indication. The MAX1508Y and MAX1508Z elimi-  
nate the prequalification state to allow startup into a load  
without a battery.  
Overvoltage Protection (OVP) Above +7V  
ꢀ Charge-Current Monitor for Fuel Gauging  
ꢀ Low Dropout Voltage—130mV at 0.425A  
ꢀ Input Power-Source Detection Output (ACOK)  
ꢀ Soft-Start Limits Inrush Current  
Proprietary thermal-regulation circuitry limits the die  
temperature to +100°C when fast charging or while  
exposed to high ambient temperatures, allowing maxi-  
mum charging current without damaging the IC.  
ꢀ No Prequalification State for the MAX1508Y and  
MAX1508Z  
ꢀ Charge Status Output (CHG) for LED or  
Microprocessor Interface  
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) for the  
MAX1508 and MAX1508Z (active-high control input for  
the MAX1508Y), and an active-low input power-source  
detection output (ACOK).  
ꢀ Small 3mm x 3mm 8-Pin Thin DFN Package,  
0.8mm High  
ꢀ Active-Low Charge Enable (EN) (MAX1508 and  
MAX1508Z)  
ꢀ Active-High Charge Enable (EN) (MAX1508Y)  
Ordering Information  
The MAX1508 accepts a +4.25V to +13V supply, but dis-  
ables 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 pack-  
age with 0.8mm height.
