U2405B Fast Charge Controller for Drained NiCd/NiMH Batteries Description The fast-charge battery controller circuit, U2405B, uses bipolar technology. The IC enables the designer to create an efficient and economic charge system. The U2405B incorporates intelligent multiple-gradient batteryvoltage monitoring and mains phase control for power management. With automatic top-off charging, the integrated circuit ensures that the charge device stops regular charging before the critical stage of overcharging is achieved. It incorporates an additional algorithm for reactivating fully drained batteries especially after longtime storage. It has two LED driver indications for charge and temperature status.
