DESCRIPTION

The AIC1783 fast charge controller IC is designed for intelligent charging of NiMH or NiCd batteries without the risk of overcharge. -?V detection (-0.25) and 0?V detection (peak voltage timer) are the primary methods employed by the AIC1783 to terminate fast charge. The fast charge can also be cut off by maximum battery voltage along with the safety timer to prevent charging under fault conditions of the charging system or the battery itself.

The safety timer period is adjustable for flexible usage that AIC1783 could be applied in the wide range of battery capacity. Test mode is provided for charger manufactures to dramatically reduce production test time.
