Single Cell Li-Ion Battery Linear Charger Accepting  
USB and AC-Adapter Power Sources  
Features  
General Description  
„
No External Power MOSFET, Sense Resistor or  
The G5880 series are a standalone linear Li-Ion bat-  
tery charger with a complete precharge, constant cur-  
rent, and constant voltage charge loop. The G5880  
series offer integrated two power source, USB-port  
and ac-adapter with autonomous power source selec-  
tion, power MOSFET, charge status, high accuracy  
current and voltage regulation, and charge termina-  
tion.  
Blocking Diode Required

1% Regulation Voltage Accuracy  
Accepting USB and AC-Adapter Power Sources  
with Autonomous Power-Source Selection  
Overvoltage Lockout for Adapter and USB Input  
USB Control For Selectable 100mA and 500mA  
Charge Rate  
„
„
„
Programmable Charge Current Limit up to 1A  
From AC-adapter  
In the USB configuration, 100mA or 500mA of charge  
rates could be selected by ISET2. In the ac-adapter  
configuration, charge current can be set by an external  
resistance.

Automatic Recharge  
Complete Precharge, Constant Current,  
Constant Voltage and Charge Termination  
Charge Procedure with Safety Timer  
Support for 5V Power Supply Voltage  
Optional Power Good Indication (AC Adapter  
Present)  
„
„
„
The charge voltage is regulated at 4.2V, and G5880  
series charge cycle would be terminated automatically  
based on minimum current after the final regulation  
voltage is reached. An internal charge timer provides a  
backup safety for charge termination. Other features  
include undervoltage lockout, overvoltage lockout,  
over temperature protection and auto-recharge if the  
battery voltage falls below an internal threshold.
