LTC4413-1/LTC4413-2 Dual 2.6A, 2.5V to 5.5V Fast Ideal Diodes in 3mm 3mm DFN Fea T Descrip T n 2-Channel Ideal Diode ORing or Load Sharing The LTC 4413-1 and LTC4413-2 each contain two mono- n Low Loss Replacement for PowerPath ORing lithic ideal diodes, each capable of supplying up to 2.6A Diodes from input voltages between 2.5V and 5.5V. The ideal n Fast Response Replacement for LTC4413 diodes use a 100m P-channel MOSFET to independently n Low Forward On-Resistance (140m Max at 3.6V) connect INA to OUTA and INB to OUTB. During normal n Low Reverse Leakage Current forward operation, the voltage drops across each of n Low Regulated Forward Voltage (18mV Typ) these diodes are regulated to as low as 18mV. Quiescent n Overvoltage Protection Sensor with Drive Output for current is less than 80A for diode currents up to 1A. If an External P-Channel MOSFET (LTC4413-2 Only) either of the output voltages exceeds its respective input n 2.5V to 5.5V Operating Range voltage, that MOSFET is turned off and less than 1A of n 2.6A Maximum Forward Current reverse current flows from OUT to IN. Maximum forward n Internal Current Limit Protection current in each MOSFET is limited to a constant 2.6A and n Internal Thermal Protection internal thermal limiting circuits protect the part during n Status Output to Indicate if Selected Channel is fault conditions. An internal overvoltage protection sensor Conducting detects when a voltage exceeds the LTC4413-2 absolute n Programmable Channel On/Off maximum voltage tolerance. n Low Profile (0.75mm) 10-Lead 3mm 3mm DFN Two active-high control pins independently turn off the two Package ideal diodes contained within the LTC4413-1/LTC4413-2. When the selected channel is reverse biased, or the a T LTC4413-1/LTC4413-2 is put into low power standby, the n Battery and Wall Adapter Diode ORing in Handheld status signal is pulled low by an 11A open drain.
