LTC4413EDD-1#PBF

LTC®4413-1 contains two monolithic ideal diodes, capable of supplying up to 2.6A from input voltages between 2.5V and 5.5V. The ideal diodes use a 100mohm P-channel MOSFET to independently connect INA to OUTA and INB to OUTB. During normal forward operation, the voltage drops across each of these diodes are regulated to as low as 18mV. Quiescent current is less than 80µA for diode currents up to 1A. If either of the output voltages exceeds its respective input voltage, that MOSFET is turned off, and less than 1µA of reverse current flows from OUT to IN. Application includes battery and wall adapter diode OR’ing in handheld products, backup battery diode OR’ing, power switching, USB peripherals, uninterruptable supplies.
