ICS1700A

QuickSaver® Charge Controller for Nickel-Cadmium

and Nickel-Metal Hydride Batteries

General Description

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 controller has four

user-selectable charge rates available for customized charging

systems. The ICS1700A is a pin-for-pin replacement for the

original ICS1700 controller.

The ICS1700A monitors for the presence of a battery and begins

charging if a battery is installed within the first 10 seconds after a

reset. Voltage and temperature are measured to ensure a battery is

within fast charge conditions before charge is initiated.
