The LTC
4058 is a complete constant-current/constant-
voltage linear charger for single cell lithium-ion batteries.
Its DFN package and low external component count make
the LTC4058 ideally suited for portable applications. Fur-
thermore, the LTC4058 is designed to work within USB
power specifications.
The LTC4058 can Kelvin sense the battery terminal for
more accurate float voltage charging. No external sense
resistor or external blocking diode are required due to the
internal MOSFET architecture. Thermal feedback regu-
lates the charge current to limit the die temperature during
high power operation or high ambient temperature condi-
tions. The charge voltage is fixed at 4.2V and the charge
current is programmed with a resistor. The LTC4058
terminates the charge cycle when the charge current
drops to 10% of the programmed value after the final float
voltage is reached.
When the input supply (wall adapter or USB supply) is
removed, the LTC4058 enters a low current state dropping
the battery drain current to less than 2
μ
A. Other features
include charge current monitor, undervoltage lockout,
automatic recharge and status pins to indicate charge
termination and the presence of an input voltage.
