The ICS1702 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 ICS1702 employs a four stage charge sequence
that provides a complete recharge with-out overcharging. The
controller has nine user-selectable charge rates and six userselectable auxiliary modes available for customized charging
systems.
The ICS1702 monitors for the presence of a battery and begins
charging when a battery is installed. Voltage and temperature are
measured to ensure a battery is within fast charge conditions before
charge is initiated.
