LP4062-00 |
The LP4062 is a complete constant-current/constantvoltage
linear charger for single cell lithium-ion batteries.
Its ThinSOT package and low external component count
make the LP4062 ideally suited for portable applications.
Furthermore, the LP4062 is specifically designed to work
within USB power specifications. No external sense resistor
is needed, and no blocking diode is required due to the
internal MOSFET architecture. Thermal feedback regulates
the charge current to limit the die temperature during high
power operation or high ambient temperature. The charge
voltage is fixed at 4.2V, and the charge current can be
programmed externally with a single resistor. The LP4062
automatically terminates the charge cycle when the charge
current drops to 1/10th the programmed value after the final
float voltage is reached. Other features include charge
current monitor, under-voltage lockout, automatic recharge
and a status pin to indicate charge termination and the
presence of
