Global Mixed-mode Technology
Single Cell Li-Ion Battery Linear Charger
Features
General Description
The G5805 is a standalone linear Li-Ion battery
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
Programmable Constant Charge Current Limit
up to 800mA
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. After the final regulation voltage is
reached and the charge current drops to 1/10th the
programmed charge current, the open drain NMOS
Automatic Recharge
Complete Pre-Charge, Constant Current,
Constant Voltage and Charge Termination
Charge Procedure
Support for 5V Power Supply Voltage
Internal Thermal Protection Circuit
TSOT-23-5 Package
CHRG pin would be turn off automatically without
terminating the charge loop.
Applications
Other features include under voltage lockout, auto-
matic recharge, over temperature protection and a
charge status indication pin.
MP3 Players
Cellular Phones
