AIC1781 Datasheet (Analog Intergrations Corporation)

AIC1781, Battery Charge Controller

The AIC1781 fast charge controller IC is designed for intelligent charging of NiMH or NiCd batteries without the risk of overcharge.

*∆V detection (-0.25%), 0 ∆V detection (peak voltage timer) and ∆T / ∆t detection are the primary methods employed by the AIC1781 to terminate fast charge.

The

AIC1781 Features
