ICS1722 General Description
The ICS1722 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 ICS1722 employs a four stage charge sequence that provides a complete recharge without overcharging. The controller has nine userselectable charge rates and six user-selectable auxiliary modes vailable for customized charging systems.
The ICS1722 monitors for the presence of a battery and begins charging when a battery is installed. The ICS1722 is for applications where temperature sensing is not required by the charge controller.
ICS1722 Maximum Ratings
| Supply Voltage | 6.5 | V |
| Logic Input Levels | -0.5 to VDD + 0.5 | V |
| Ambient Operating Temperature | 0 to 70 | |
| Storage Temperature | -55 to 150 |
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.
