ICS1702
QuickSaver Charge Controller for Nickel-Cadmium
and Nickel-Metal Hydride Batteries
General Description
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 user-
selectable 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.
Applications
Battery charging systems for:
-
Portable consumer electronics
-
Power tools
-
Audio/video equipment
-
Communications equipment
-
Portable medical electronics
