  SE9020  Standalone Linear Lithium Battery Charger 咨詢此產品

SE9020 is a complete Limit-current & constant voltage charger for single cell Lithium-ion and Lithium-Polymer batteries. Its SOT-23-6L package and low external component count make SE9020 ideally suited for portable applications. Furthermore, the SE9020 is specifically designed to work within Universal Travel Charger.

SE9020 has a built-in detector that will automatically detect the polarity of the inserted battery and charge the battery at the correct the polarity. The charge voltage is fixed at 4.2V. The SE9020 automatically terminates the charge cycle when the charge current drops to 14mA after the final float voltage is reached.

When the input supply is removed, the SE9020 automatically enters a low current stage, dropping the battery drain current to less than 7mA.  The SE9020 can be put into shutdown mode, reducing the supply current to 30uA.

SE9020 supports two LED drivers that give the customers the option to select which method fit best in their respective applications. One LED driver is internally set to indicate the power on/off of the IC. Another LED driver can either drive a standard LED or 7-color LED IC, which will be explained in detail in the application notes.
