DESCRIPTION  
FEATURES  
n
Full Featured Li-Ion/Polymer Charger/PowerPath™  
The LTC®3577 is a highly integrated power management  
IC for single cell Li-Ion/Polymer battery applications. It  
includesaPowerPathmanagerwithautomaticloadpriori-  
tization,abatterycharger,anidealdiode,inputovervoltage  
protectionandnumerousotherinternalprotectionfeatures.  
TheLTC3577isdesignedtoaccuratelychargefromcurrent  
limited supplies such as USB by automatically reducing  
charge current such that the sum of the load current and  
thechargecurrentdoesnotexceedtheprogrammedinput  
current limit (100mA or 500mA modes). The LTC3577  
reduces the battery voltage at elevated temperatures to  
improve safety and reliability. Efficient high current charg-  
ing from supplies up to 38V is available using the on-chip  
Bat-Track controller. The LTC3577 also includes a push-  
button input to control the three synchronous step-down  
switching regulators and system reset. The onboard LED  
backlight boost circuitry can drive up to 10 series LEDs
