镍氢充电器设计

INTRODUCTION
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.
