ICS1700A - ETC

ICS1700A QuickSaver Charge Controller for Nickel-Cadmium and Nickel-Metal Hydride Batteries

The ICS1700A is a CMOS device designed for the intelligent charge control of either nickel-cadmium (NiCd) or nickel-metal hydride (NiMH) batteries. The controller uses a pulsed-current charging technique together with voltage slope termination. The ICS1700A employs a four stage charge sequence that provides a complete recharge without overcharging. The contr.
