Simple Current-Limited Switch-Mode  
Li+ Charger Controller  
General Description  
Features  
The low-cost MAX1873R/S/T provides all functions  
needed to simply and efficiently charge 2-, 3-, or 4-  
series lithium-ion cells at up to 4A or more. It provides a  
regulated charging current and voltage with less than  
±±.7ꢀ5 total voltage error at the ꢁattery terminals. An  
external P-channel MOSFET operates in a step-down  
DC-DC configuration to efficiently charge ꢁatteries in  
low-cost designs.  
ꢀ Low-Cost and Simple Circuit  
ꢀ Charges 2-, 3-, or 4-Series Lithium-Ion Cells  
ꢀ AC Adapter Input-Current-Limit Loop  
ꢀ Also Charges Ni-Based Batteries  
ꢀ Analog Output Monitors Charge Current  
ꢀ ±±0.75 Batterꢀ-ꢁegulation ꢂoltage  
ꢀ 7µA Shutdown Batterꢀ Current  
The MAX1873R/S/T regulates the ꢁattery voltage and  
charging current using two control loops that work  
together to transition smoothly ꢁetween voltage and  
current regulation. An additional control loop limits cur-  
rent drawn from the input source so that AC adapter  
size and cost can ꢁe minimized. An analog voltage out-  
put proportional to charging current is also supplied so  
that an ADC or microcontroller can monitor charging  
current.  
ꢀ Input ꢂoltage Up to 28ꢂ  
ꢀ 2±±mꢂ Dropout ꢂoltage/1±±5 Dutꢀ Cꢀcle  
ꢀ Adjustable Charging Current  
ꢀ 3±±kHz PWM Oscillator ꢁeduces Noise  
ꢀ Space-Saving 16-Pin QSOP  
The MAX1873 may also ꢁe used as an efficient current-  
limited source to charge NiCd or NiMH ꢁatteries in mul-  
tichemistry charger designs. The MAX1873R/S/T is  
availaꢁle in a space-saving 16-pin QSOP package. Use  
the evaluation kit (MAX1873EVKIT) to help reduce  
design time.
