Battery Charge Controller

The AIC1761 AIC1766 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 batter- ies. The AIC1761 AIC1766 uses -V detection as one of primary decisions for fast charge cut-off. The - V value for the AIC1761 is as small as 16mV per cell, suitable for NiCd batteries. The -V value for the AIC1766 is as small as 4mV per cell, particularly suitable for NiMH as well as the NiCd batteries. The peak voltage Timer is particu- larly 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 ad- justable safety Timer (3 settings) is used as a back- up termination method. Provisions are made with the AIC1761 AIC1766 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 Analog Devices, Inc.
