DESCRIPTION
The LTC ? 4063 is a standalone linear charger for single cell
lithium-ion batteries with an adjustable low dropout linear
regulator (LDO). The adjustable LDO regulates an output
voltage between 1.2V to 4.2V at up to 100mA load cur-
rent. When the input supply (wall adapter or USB supply)
is removed, the LDO regulates the output voltage without
interruption. The battery charger and LDO regulator can
be enabled individually.
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 conditions.
The float voltage is fixed at 4.2V and the charge current is
programmed with an external resistor. Charge termination
methods include minimum charge current or maximum
time. With power applied, the LTC4063 can be put into
shutdown mode to reduce the supply current to 35μA and
the battery drain current to less than 2μA.
Other features include smart recharge, undervoltage
lockout, LDO current limiting and a charge status pin to
indicate when the charge cycle has completed.
