SGM4056 pdf资料下载The SGM4056 is a cost-effective, fully integrated high input voltage single-cell Li-ion battery charger. The charger uses a CC/CV charge profile required by Li-ion battery. The charger accepts an input voltage up to 26.5V but is disabled when the input voltage exceeds the OVP threshold, typically 6.8V (SGM4056-6.8) or 10.5V (SGM4056-10.5), to prevent excessive power dissipation. The 26.5V rating eliminates the overvoltage protection circuit required in a low input voltage charger. The charge current and the end-of-charge (EOC) current are programmable with external resistors. When the battery voltage is lower than typically 2.55V, the charger preconditions the battery with typically 18% of the programmed charge current. When the charge current reduces to the programmable EOC current level during the CV charge phase, an EOC indication is provided by the CHG pin, which is an open-drain output. An internal thermal foldback function protects the charger from any thermal failure.
