The LTC ? 4062 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 applica-
tion. A precise low power comparator is available even
with no power applied as long as battery voltage is higher
than 2.5V. Additional safety features designed to maxi-
mize battery lifetime and reliability include the SmartStart
charging algorithm.
No external sense resistor or external blocking diode is
required for charging due to the internal MOSFET architec-
ture. Internal thermal feedback regulates the charge cur-

TYPICAL APPLICATIO
rent to maintain a constant die temperature during high
power operation or high ambient temperature conditions.
The charge current is programmed with an external resis-
tor. With power applied, the LTC4062 can be put into
shutdown mode to reduce the supply current to 20 μ A and
the battery drain current to less than 5 μ A. Without power
applied, the internal low power comparator can work
sinking only 10 μ A from the battery.
Other features include smart recharge, USB C/5 current
programming input and undervoltage lockout.
