XT2058 Datasheet | Silinktek

Single Li-ion Battery Charger With Thermal Regulation - General Description The XT2058 is a plete constant-current /constant -voltage linear charger for single cell Li-ion battery. Its Thin SOP package and low external ponent count make the XT2058 ideally suited for portable applications. 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 XT2058 automatically terminates...
