Download Datasheet Visit Manufacturer Site View Pricing & Stock

The LTC3350 is a backup power controller that 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. The LTC3350 is available in a low profile 38-lead 5mm × 7mm × 0.75mm QFN surface mount package.

Demonstration circuit 1937B is a supercapacitor charger and backup controller with supercapacitor health and system monitoring; featuring the LTC®3350. The LTC3350 has a buck supercapacitor charger, backup boost controller and an input ideal diode to disconnect the input supply in backup mode. An output ideal diode allows the supercapacitors to supply the output when VCAP is above the set backup voltage. As the capacitor stack voltage drops PERFORMANCE SUMMARY
