U2402B-C

U2402B-C Fast Charge Controller for NiCd/NiMH Batteries Description The fast charge battery controller circuit, U2402B-C, uses bipolar technology. It enables an efficient and economic charge system. It incorporates intelligent multiple gradient battery voltage monitoring and mains phase control for power management. With automatic top-off charging, the integrated circuit enables the charge device to stop regular charging, before the critical stage of overcharging can occur. It has two LED driver indications for charge and temperature status. Features D Multiple gradient monitoring D Temperature window (Tmin/Tmax) D Exact battery voltage measurement without charge D Phase control for charge current regulation D Top off and trickle charge function D Two LED outputs for charge status indication D Disabling of d2V/dt2 switch-off criteria during battery formation D Battery voltage check Applications D Portable power tools D Laptop/notebook personal computer D Cellular/cordless phones D ...
