TYPICAL APPLICATION
800mA Single-Cell Li-Ion Battery Charger
(C/10 Termination)
DESCRIPTION
The LTC ? 4061 is a full-featured, flexible, standalone linear
charger for single-cell Lithium-Ion batteries. It is capable
of operating within USB power specifications.
Both programmable time and programmable current
based termination schemes are available. Furthermore,
the CHRG open-drain status pin can be programmed to
indicate the battery charge state according to the needs
of the application. Additional safety features designed
to maximize battery lifetime and reliability include NTC
battery temperature sensing and the SmartStart charg-
ing algorithm.
No external sense resistor or external blocking diode is
required for charging due to the internal MOSFET archi-
tecture. Internal thermal feedback regulates the charge
current to maintain a constant die temperature during
high power operation or high ambient temperature condi-
tions. The charge current is programmed with an external
resistor. With power applied, the LTC4061 can be put into
shutdown mode to reduce the supply current to 20μA and
the battery drain current to less than 5μA.
Other features include smart recharge, USB C/5 cur-
rent programming input, undervoltage lockout and AC
Present logic output.
