Description
The ICS1702 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.
Key Features
- Multiple charge termination methods include: Voltage slope Temperature 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
- Nine programmable charge rates between 15 minutes (4C) and four hours (C/4)
- Out-of-temperature range detection Hot battery: charger shutdown Cold battery: low current charge
- Continuous polling mode for battery detection
- Adjustable open circuit (no battery) voltage reference
