• Programmed parameters - modified in firmware
• Factory Settings:
• Preconditioning Charge Current = 200 mA
• Preconditioning Threshold = 3 V
• Constant Current Fast Charge = 2 A
• Constant Voltage Charge = 4.2 V
• Charge Termination Threshold = 100 mA
• Overvoltage protection (battery removed)
• Over charge protection
• Over current protection
• Overtemperature protection
• Fast charge termination if the battery temperature is outside a preset window
• Controlled soft-start
• Terminates charge by detecting a predefined charge current threshold during constant voltage charge, or a specified elapsed time
• Has the flexibility to optimize the charging algorithm for new battery technology
