镍氢/镍镉电池开关模式电池充电器的dV / dt充电终止

资料介绍
摘要:该电路包括电池充电器( MAX712 )处理充电器的电源部分和降压开关稳压器( MAX5089 ) 。通过控制稳压器为电池充电控制器MAX712的行为,生产为7V至16V的输出。从任何能够提供所需的快速充电电流,这种情况必须等于输出电压的总和(二加系列充电电池的数量)乘以1.7V的直流电源。

Abstract:This circuit includes a battery charger (MAX712) and step-down switching regulator (MAX5089) for handling the power
portion of the charger. By controlling the regulator the MAX712 acts as a battery-charge controller, producing outputs of 7V to
16V. It operates from any DC source capable of delivering the desired fast-charge current, with this condition: the output voltage
must equal 1.7V multiplied by the sum of (two plus the number of batteries to be charged in series).
