1 / 24 page  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. Applications Battery charging systems for: - Portable consumer electronics - Power tools - Audio/video equipment - Communications equipment - Wireless handsets Features • Multiple charge termination methods include: - Voltage 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 • Four programmable charge rates between 15 minutes (4C) and two hours (C/2) • Out-of-temperature range detection - Hot battery: charger shutdown - Cold battery: low current charge • Ten second polling mode for battery detection • Battery fault with shutdown protection Block Diagram CHARGE DISCHARGE TEMPERATURE SENSE SELECT CHARGE VOLTAGE SENSE PROCESSOR MICROCODE CONTROL ADC RAM ROM OUTPUT CONTROL RESET 2.0V 0.5V HOT COLD CHARGE MODE LED CONTROL CONTROL POLLING/ FAULT LED TEMPERATURE STATUS LED OSCILLATOR RC |
