EMC5754-1A线性锂电池充电管理IC


EMC5754-Standalone Linear Li-Ion Battery Charger with Thermal Regulation in SOT-25  SOP-8-EP DataSheet 
 
General Description
    The EMC5754 is a complete linear charger for single cell lithium-ion batteries. With small SOT-25 package and few external components, EMC5754 is well suited for portable applications. In addition, the EMC5754 is specifically designed to work within USB power specifications.
    No external sense resistor and blocking diode are required. Charging current can be programmed externally with a single resistor. The built-in thermal regulation facilitates charging with maximum power without risk of overheating.
    The EMC5754 always preconditions the battery with 1/10 of the programmed charge current at the beginning of a charge cycle, until 40μs after it verifies that the battery can be fast-charged. The EMC5754 automatically terminates the charge cycle when the charge current drops to 1/10th the programmed value after the final float voltage is reached.
    The EMC5754 consumes zero reverse current from the battery at standby, shutdown and sleep modes. This feature reduces the charge and discharge cycles on the battery, further prolonging the battery life. The EMC5754 can also be used as a LDO when battery is removed. Other features include shutdown mode, charge current monitor, under voltage lockout, automatic recharge and status indicator.
