ESMT/EMP EMC5042 Standalone Linear Li-Ion Charger (two-cell) with Thermal Regulation General Description The EMC5042 is a complete linear charger for two-cell lithium-ion batteries. With small TDFN-10 package and few external components, EMC5042 is well suited for portable applications. 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 EMC5042 always preconditions the battery with 1/10 of the programmed charge current at the beginning of a charge cycle, after it verifies that the battery can be fast-charged.
