Product Overview

The LTC4413EDD#PBF is a dual monolithic Ideal Diode capable of supplying up to 2.6A from an input voltage between 2.5 and 5.5V. Each ideal diode uses a 100mR P-channel MOSFET that independently connects INA to OUTA and INB to OUTB. During normal forward operation the voltage drop across each of these diodes is regulated to as low as 28mV. Quiescent current is less than 40µA for diode currents up to 1A. If either of the output voltages exceeds its respective input voltages, that MOSFET is turned off and less than 1µA of reverse current will flow from OUT to IN. Maximum forward current in each MOSFET is limited to a constant 2.6A and internal thermal limiting circuits protect the part during fault conditions. When the selected channel is reverse biased or the LTC4413 is put into low power standby, a status signal indicates this condition with a low voltage. A 9µA open-drain STAT pin is used to indicate conduction status.
  • 2-channel ideal diode ORing or load sharing
  • Low loss replacement for ORing diodes
  • Low forward ON-resistance (100mR Max at 3.6V)
  • Low reverse leakage current (1µA maximum)
  • Small regulated forward voltage (28mV typical)
  • 2.6A Maximum forward current
  • Internal current limit and thermal protection
  • Slow turn-on/off to protect against inductive source impedance-induced voltage spiking
  • Ultralow quiescent current consumption
  • Status output to indicate if selected channel is conducting
  • Programmable channel ON/OFF
