The LTC ? 4065 is a complete constant-current/constant-
voltage linear charger for single-cell lithium-ion batteries.
Its 2mm × 2mm DFN package and low external component
count make the LTC4065 especially well-suited for por-
table applications. Furthermore, LTC4065 is specifically
designed to work within USB power specifications.
The CHRG pin indicates when charge current has dropped
to ten percent of its programmed value (C/10). An internal
timer terminates charging according to battery manufac-
turer specifications.
No external sense resistor or blocking diode is required
due to the internal MOSFET architecture. Thermal feed-
back regulates charge current to limit the die temperature
during high power operation or high ambient temperature
conditions.
When the input supply (wall adapter or USB supply) is
removed, the LTC4065 automatically enters a low current
state, dropping battery drain current to less than 1 μ A. With
power applied, LTC4065 can be put into shutdown mode,
reducing the supply current to less than 20 μ A.
