Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only. Functional operation of the device at the Absolute Maximum Ratings or other conditions not consistent with the characteristics shown in this document is not recommended. Exposure to absolute maximum rating conditions for extended periods may affect product reliability.


Description

The ICS1712 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 ICS1712 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 ICS1712 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.
