Single-/Dual-Input 1-Cell Li+ Chargers with  
OVP Protection and Programmable Charge Timer  
General Description  
Features  
The MAX8600/MAX8601 single-/dual-input linear bat-  
tery chargers safely charge single-cell Li+ batteries.  
The charging rate is optimized to accommodate the  
thermal characteristics of a given application. There is  
no need to reduce the maximum charge current or  
worst-case charger power dissipation. Charging is opti-  
mized for Li+ cells using a control algorithm that  
includes low-battery precharging, voltage and current-  
limited fast-charging, and top-off charging, while con-  
tinuously monitoring the battery for overvoltage,  
over/undertemperature, and charging time. The charg-  
er timeout protection is programmable. The charger  
status is indicated by three open-drain outputs.  
Single- (MAX8600) or Dual- (MAX8601) Input Li+

Programmable On-Chip Charge Timers  
Batterꢁ Thermistor Input  
Charger-Status Outputs  
The MAX8601 automatically selects between either a  
USB or AC adapter input source. The AC adapter  
charge current is programmable, while USB charge  
current is set not to exceed either 100mA or 500mA,  
depending on the USEL input. The MAX8600 is a sin-  
gle-input charger with no USB source input.
