CN3125 Linear UltraCapacitor Charger 1A Current eSOP8
The CN3125 is a complete constant-current /constant voltage linear charger IC
to charge single cell or 2-cell superCapacitors from a power supply of 2.7V to 6V.
• Operating Voltage Range: 2.7V to 6V
• On-chip Power MOSFET
• No external Blocking Diode or Current Sense Resistors Required
• Constant Voltage is set by External Resistors
• Charge Current is set by an external resistor
• Continuous Charge Current Up to 1.5A
• Automatic Cell Balancing to Prevent Suercapacitors Overvoltage During Charging
• Constant-Current/Constant-Voltage Operation with Thermal Regulation to Maximize Charge Rate Without Risk of Overheating
• Automatic Low-Power Sleep Mode When Input Supply Voltage is Removed
• Indication for Supercapacitor Power Good
• Chip Enable Input
• Available in eSOP8 Package
• Pb-free, rohs-compliant and Halogen-free
