基于DS2770的镍氢充电器设计:In order to achieve maximum efficiency when charging a battery, it is necessary to implement charging techniques geared specifically for a battery cell chemistry. For example, negative ΔV or dT/dt termination criteria is used for NiMH cells, while a CC/CV or pulsed-charged technique is appropriate for rechargeable lithium cells.The DS2770 battery monitor and charge controller can be configured to charge either NiMH or Li+ cells. This application note addresses several key things to consider when using the DS2770 to charge a NiMH battery pack.
