SC1766 Datasheet (Semtech Corporation) - BATTERY CHARGE CONTROLLER

SC1766, BATTERY CHARGE CONTROLLER

The SC1766 fast charge controller IC is designed for intelligent charging of NiMH or NiCd batteries without overcharging.

It detects a voltage drop (-∆V) occurring in the final stage of a fast charging cycle and correspondingly controls the charging current.

Fast charge can also be cut off by a peak
