EUP8092X  
1.5A Linear Li-Ion/Polymer Charger IC  
with Integrated FET and Charger Timer  
FEATURES  
DESCRIPTION  
z
z
Very Low Power Dissipation  
The EUP8092X series are highly integrated single cell  
Li-Ion/Polymer battery charger IC designed for handheld  
devices. This charger is designed to work with various  
types of AC adapters or a USB port and capable of  
operating with an input voltage as low as 2.65V.  
Accepts Multiple Types of Adapters or USB BUS  
Power  
z
Integrated Power FET and Current Sensor for Up  
to 1.5A Charge Applications  
The EUP8092X operates as a linear charger and charges  
the battery in three phases: trickle current, constant current,  
and constant voltage. When AC-adapter is applied, an  
external resistor sets the magnitude of the charge current,  
which may be programmed up to 1.5A with TDFN10  
package and a current-limited adapter for lowest power  
dissipation.

Precharge Conditioning With Safety Timer  
Reverse Leakage Protection Prevents Battery  
Drainage  
The EUP8092X features thermal regulation loop to control  
charge current to keep safe operation when PCB lacked of  
enough heat-sinking. A programmable charge timer  
provides a backup safety for termination. The EUP8092X  
automatically re-starts the charge if the battery voltage  
falls below an internal threshold and automatically enters  
sleep mode when DC supplies are removed. No external  
sense resistor or blocking diode is required for charging. A  
NTC thermistor interface is used for charging the battery  
in a safe temperature range.
