ICS1708 - QuickSaver Charge Control IC for Nickel-Cadmium and Nickel-Metal Hydride Batteries

General Description

The ICS1708 is a low cost 8 pin CMOS control IC for the intelligent charging of either nickel-cadmium (NiCd) or nickel-metal hydride (NiMH) batteries.

The ICS1708 uses a pulsed-current charging technique together with multiple voltage slope termination methods.

Key Features

  • Charge termination methods include: Voltage slope (+∆V/dt and +/- peak detect), and Fast charge time out to maintenance mode Four stage charge sequence: SoftStart conditioning, Fast charge, Topping charge, and Maintenance charge Three (3) user selectable charge rates: 15 minutes (4C), 60 minutes (1C), 150 minutes (C/2.5) Continuous polling mode for battery detection Adjustable open circuit (no battery) volt.

ICS1708 QuickSaver® Charge Control IC for Nickel-Cadmium and Nickel-Metal Hydride Batteries General Description The ICS1708 is a low cost 8 pin CMOS control IC for the intelligent charging of either nickel-cadmium (NiCd) or nickel-metal hydride (NiMH) batteries. The ICS1708 uses a pulsed-current charging technique together with multiple voltage slope termination methods. The ICS1708 employs a four stage charge sequence that provides a complete recharge without overcharging. The controller has three (3) user selectable charge rates, user accessible clock, and two (2) charge status output pins. On power-up, the ICS1708 monitors for the presence of a battery and begins charging. The ICS1708 is for applications where battery temperature protection is not required of the charge controller.
