ICS1712

QuickSaver® Charge Controller for Nickel-Cadmium

and Nickel-Metal Hydride Batteries

General Description

The ICS1712 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 and/or temperature slope

termination. The ICS1712 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 ICS1712 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.
