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.APPLICATIONS High Current 12V Ride-Through UPS Servers/Mass Storage/High Availability Systems
