Global Mixed-mode Technology Inc.
G5880/G5881/G5882
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.
Optional Battery Temperature Monitoring
Internal Thermal Protection Circuit
3mm × 3mm TDFN Package
Applications
MP3 Players
Cellular Phones, Smartphone
PDAs, Digital Cameras
Hand-Held Devices
