CN3062

www.DataSheet.co.kr CONSONANCE 600mA USB-Compatible Lithium Battery Charger CN3062 General Description: The CN3062 is a complete constant-current /constant voltage linear charger for single cell lithium rechargeable battery. The device contains an on-chip power MOSFET and eliminates the need for the external current sense resistor and blocking diode. Furthermore, the CN3062 is specifically designed to work within USB power specifications. Its low external component count makes CN3062 ideally suited for portable applications. Thermal feedback regulates the charge current to limit the die temperature during high power operation or high ambient temperature. The regulation voltage is internally fixed at 4.2V, it can also be adjusted with an external resistor. The charge current can be programmed externally with a single resistor. When the input supply (wall adapter or USB supply) is removed, the CN3062 automatically enters a low power sleep mode, dropping the battery drain current to less than 3uA. Other features include under-voltage lockout, automatic recharge, battery temperature sensing and charging/termination indicator. The CN3062 is available in a thermally enhanced 8-pin SOP package.
