The SC70561B is a highly integrated linear charger for 1cell Li-ion battery applications. It supports up to 500mA charging current and provides battery charge management functions including trickle charge, constant current charge, constant voltage charge, charge termination and charging status indication. No external sense resistor is needed, and no blocking diode is required. Furthermore, the SC70561B is specifically designed to work with in USB power specifications. Its low external component count makes the SC70561B ideally suited for portable applications. Thermal feedback regulates the charge current to limit their temperature during high power operation or high ambient temperature. The charge current and termination current can be programmed independently with external resistor. The SC70561B automatically terminates the charge cycle when the charge current drops to the programmed value after the final float voltage is reached. When the input supply (wall adapter or USB supply) is removed, the SC70561B automatically enters a low power sleep mode, dropping the battery drain current to less than 0.25μA. The SC70561B can be put into shutdown mode, also reducing the supply current to 0.25μA.Other features include battery pack temperature monitor, under voltage lockout, battery reserve insert protection ,automatic recharge and two status pins to indicate charging and charge termination.The SC70561B also supports input voltage limit (VINDPM). When input source is over-loaded, the input voltage falls below the input voltage limit (VINDPM). The device then reduces the charge current until the input voltage rises above the input voltage limit.SC70561B is available in DFN 2X2 Package.
