Exposure to absolute maximum rating conditions for extended periods affects product reliability.


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.
