GC1261 Data Sheet Information
GC8051
1 Cell Li-ion Battery Charger
1. OVERVIEW
The GC8051 is a single Lithium-Ion (Li-Ion) and
Lithium–Polymer (Li-Pol) linear charge management
controller for use in cost sensitive and portable
applications. It combines high accuracy
constant-current and constant-voltage regulation,
cell preconditioning, temperature monitoring,
automatic charge termination, charge-status
indication, in a space-saving MSOP-8 package.
The GC8051 applies a constant current up to 1A to
the battery and the charge current can be
programmed externally with a sense-resistor.
The GC8051 automatically terminates the charge
cycle when the charge current drops to the charge
termination threshold (ITERM) after
charge-regulation voltage is reached.
the
When the input supply is removed, the GC8051
automatically enters a low-power sleep mode,
dropping the battery drain current to less than 1µA.
A battery charge state output pin is provided to
indicate battery charge status through a display LED.
The battery charge status output is a serial interface
which may also be read by a system microcontroller.
2. FEATURES
Programmable Charge Current up to 1A
4.5V-7V Input Voltage Range
Ideal for Single Cell (4.1V or 4.2V) Li-Ion or
Li-Pol Batteries
Preset Charge Voltage with ±1% Accuracy
Constant-Current/Constant Voltage Operation
Preconditioning of Low Voltage Cells
Optional Cell-Temperature Monitoring Before
and During Charge
Charge Status Indication
Automatic Battery Recharge
Charge Termination by Minimum Current
Automatic Low-Power Sleep Mode When Input
Power is Removed
Available in MSOP-8 Package
RoHS Compliant and 100% Lead (Pb)-Free
3. APPLICATIONS
Chargers for MP3, Digital Camera, Hand-Held
home appliance.
