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 voltage Timer (0V). The detection of -V is a very reliable method to terminate fast charging for NiMH and NiCd batteries. The SC1766 uses -V detection as one of the primary decisions for fast charge cut-off. The -V value of the SC1766 is as small as 4mV per cell, particularly suitable for NiMH as well as NiCd batteries. The peak voltage Timer is particularly useful when the voltage drop at the end of charge for some batteries, e.g. NiMH cells, is not pronounced enough for reliable detection. An adjustable safety Timer (3 settings) is used as a backup termination method. Provisions are made with the SC1766 to prevent fast charge under temperature fault conditions. Two LED outputs are used to indicate the charging status. Another Flash LED output CAN be used alone to indicate charge status. By Semtech Corporation
