LTC4096/LTC4096X  
Dual Input Standalone  
Li-Ion Battery Chargers  
FEATURES  
DESCRIPTION  
The LTC®4096/LTC4096X are standalone linear chargers  
that are capable of charging a single-cell Li-Ion or Li-Poly-  
mer battery from both wall adapter and USB inputs. The  
chargers can detect power at the inputs and automatically  
select the appropriate power source for charging.  
■
Charges Single-Cell Li-Ion Battery from Wall  
Adapter and USB Inputs  
■
Automatic Input Detection (DC Input has Charging  
Priority)  
■
Charge Current Programmable up to 1.2A from  
Wall Adapter Input  
C/X Charge Current Termination  
No external sense resistor or blocking diode is required  
for charging due to the internal MOSFET architecture.  
Internal thermal feedback regulates the battery charge  
currenttomaintainaconstantdietemperatureduringhigh  
power operation or high ambient temperature conditions.  
The float voltage is fixed at 4.2V and the charge current  
is programmed with an external resistor. The LTC4096  
terminatesthechargecyclewhenthechargecurrentdrops  
below the user programmed termination threshold after  
the final float voltage is reached. The LTC4096 can be put  
into shutdown mode reducing the DCIN supply current to  
20µA, the USBIN supply current to 10µA, and the battery  
drain current to less than 2µA even with power applied  
to both inputs.
