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.
