General Description

The LTC®3351 is a backup power controller that charges and monitors a series stack of one to four supercapacitors.

The LTC3351’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 runs in reverse as a step-up converter to deliver power from the supercapacitor stack to the backup supply rail.

Key Features

n Integrated Hot Swap Controller with Circuit Breaker n High Efficiency Synchronous Step-Down CC/CV Charging of One to Four Series Supercapacitors n Step-Up Mode in Backup Provides Greater Utilization of Stored Energy in Supercapacitors n 16-Bit ADC for Monitoring System Voltages/ Currents, Capacitance and ESR n Programmable Undervoltage and Overvoltage Thresholds to 35V n VIN: 4.5V to 35V, VCAP(n): Up to 5V per Capacitor, Charge/Backup Current: >10A n Programmable Input Current Limit Prioritize.
