The LTC3350EUHF#PBF is a high current supercapacitor Backup Controller and System Monitor can charge and monitor a series stack of one to four supercapacitors. The LTC3350's synchronous step-down controller drives N-channel MOSFETs for constant current/constant voltage charging with programmable input current limit. In addition, the step-down converter can run in reverse as a step-up converter to deliver power from the supercapacitor stack to the backup supply rail. Internal balancers eliminate the need for external balance resistors and each capacitor has a shunt regulator for overvoltage protection. The LTC3350 monitors system voltages, currents, stack capacitance and stack ESR which can all be read over the I2C/SMBus. The dual ideal diode controller uses N-channel MOSFETs for low loss power paths from the input and supercapacitors to the backup system supply.

• High efficiency synchronous step-down CC/CV charging of one to four series supercapacitors
• Step-up mode in backup provides greater utilization of stored energy in supercapacitors
• 14-bit ADC for monitoring system voltages/currents, capacitance and ESR
• Active overvoltage protection shunts
• Internal active balancers, no balance resistors
• Programmable input current limit prioritizes system load over capacitor charge current
• Dual ideal diode PowerPath? controller
• All N-FET charger controller and PowerPath? controller
