ICS1702

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 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. Features Multiple charge termination methods include: Voltage slope Temperature slope Maximum temperature Charge timer Four stage charge sequence: Soft start charge Fast charge Topping charge Maintenance charge Reverse-pulse charging available in all charge stages Nine programmable charge rates between 15 minutes (4C) and four hours (C/4) Out-of-temperature range detection Hot battery: charger shutdown Cold battery: low current charge Continuous polling mode for battery detection Six auxiliary modes include: Discharge-before-charge Ten hour C/10 conditioning charge Direct to C/40 maintenance charge Charging system test provided through ...
