G5808
Single Cell Li-Ion Battery Linear Charger
Features
General Description
The G5808 is a complete standalone linear Li-Ion bat-
tery charger with a complete pre-charge, constant-
current and constant-voltage charge loop.
No External Power MOSFET, Sense Resistor or
Blocking Diode Required
1% Regulation Voltage Accuracy
Charge Single Cell Li-ion Battery from AC
Adapter or USB Port
No external power MOSFET, sense resistor and block-
ing diode is required due to internal power MOSFET
architecture. The charge voltage is regulated at 4.2V,
and the charge current is programmable by an exter-
nal resistor up to 2A. After the final regulation voltage
is reached and the charge current drops to the pro-
grammed end-of-charge current, the open drain
Programmable Constant Charge Current Limit
up to 2A
Automatic Recharge
Complete Pre-Charge, Constant Current,
Constant Voltage and Charge Termination
Charge Procedure
NMOS STATUS pin would be turn off automatically
and the charge loop would be terminated after timeout.
NTC Thermistor Interface for Battery Tempera-
ture Detection
Internal input Overvoltage Lockout Protection
Circuit (VIN >6.5V)
Other features include under voltage lockout, auto-
matic recharge, an NTC thermistor interface for
charging the battery in a safe range, over temperature
protection and two charge status indication pins.
Support for 5V Power Supply Voltage
Internal Thermal Protection Circuit
