• Programmed parameters - modified in firmware
• Factory Settings:

            - Preconditioning Charge Current =170 mA

            - Preconditioning Threshold = 3 V

            - Constant Current Fast Charge = 1.35 A

            - Charge Termination based on delta - VBATT / delta time

            - Charge Termination based on delta + TBATT / delta time, with external thermistor installed

• Top Off Charge Current = 130 mA for 1 Hour
• Overvoltage protection (battery removed)
• Overcharge protection to prevent damaging the battery
• Overcurrent protection in the event of a shorted battery
• Battery reversal protection
• Input short circuit protection
• Overtemperature protection to prevent the battery from reaching too high a temperature during charge
• Soft-start capability by holding the reference voltage low during power-up
• The MCP1630 Low-Cost NiMH Battery Charger has the flexibility to optimize the charging algorithm for new battery technology, different battery chemistries or different battery pack configurations
• Proprietary features can be added by modifying the firmware contained in the PIC12F683
• The factory-programmed source code is available
• Ability to adapt to environmental effects, such as ambient temperature
