Stand-Alone, Switch-Mode  
Li+ Battery Charger with Internal 14V Switch  
General Description  
Features  
o Stand-Alone Charger for Up to 3 Li+ Batteries  
The MAX1757 is a switch-mode lithium-ion (Li+) battery  
charger that charges one to three cells. It provides a  
regulated charging current accurate to 1ꢀ0 and a  
regulated voltage with only a ꢀ.ꢁ0 total voltage error  
at the battery terminals. The internal high-side switch  
delivers a programmable current of up to 1.5A to  
charge the battery. The built-in safety timer automatical-  
ly terminates charging once the adjustable time limit  
has been reached.  
o ±±0.8 Batterꢀ ꢁegꢂlation ꢃoltage Aꢄꢄꢂraꢄꢀ  
o Low-Dropoꢂt 9.8 Dꢂtꢀ Cꢀꢄle  
o Safelꢀ Preꢄharges Near-Dead Cells  
o Continꢂoꢂs ꢃoltage and Temperatꢂre Monitoring  
o ±01µA Shꢂtdown Batterꢀ Cꢂrrent  
o Inpꢂt ꢃoltage Up to 14ꢃ  
The MAX1757 regulates the voltage set point and  
charging current using two loops that work together to  
transition smoothly between voltage and current regula-  
tion. An additional control loop monitors the total cur-  
rent drawn from the input source (charging + system)  
and by automatically reducing battery-charging current  
prevents overload of the input supply, allowing the use  
of a low-cost wall adapter.  
o Up to 105A Programmable Charge Cꢂrrent  
o Inpꢂt Cꢂrrent Limiting  
o Spaꢄe-Saving 2.-Pin SSOP  
o 3±±kHz PWM Osꢄillator ꢁedꢂꢄes Noise  
The per-cell battery regulation voltage is set between  
4.ꢀV and 4.4V using standard 10 resistors. The num-  
ber of cells is set from 1 to 3 by pin strapping. Battery  
temperature is monitored by an external thermistor to  
prevent charging outside the acceptable temperature  
range.  
The MAX1757 is available in a space-saving 2ꢁ-pin  
SSOP package. Use the MAX1757EVKIT to help reduce  
design time. For a stand-alone charger with a 2ꢁV  
switch, refer to the MAX175ꢁ data sheet. For a charger  
controller capable of up to 4A charging current, refer to  
the MAX1737 data sheet.
