Chipower CE3102
The CE3102 is a complete constant-current constant-voltage linear charger for small current Li-Ion button battery. It’s SOT package and low external component count make the CE3102 especially well-suit for portable applications. The charge voltage is fixed at 4.2V and the charge current can be programmed externally with a single resistor.FEATURES
