LTC4413EDD#PBF

LTC4413 is a dual, ideal diode. It contains two monolithic ideal diodes, each capable of supplying upto 2.6A from input voltages between 2.5V and 5.5V. Each ideal diode uses a 100mΩ 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 upto 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. It is widely used in applications such as battery and wall adapter diode ORing in handheld products, backup battery diode ORing, power switching, USB peripherals, uninterruptable supplies etc.

• Low loss replacement for ORing diodes
• Internal current limit and thermal protection
• Slow turn-On/Off to protect against inductive source impedance-induced voltage spiking
• Ultralow quiescent current consumption, low power alternative to the LTC4413-1
• Status output to indicate if selected channel is conducting
• Programmable channel on/off
• Operating temperature is -40°C to 85°C
• Package style is 10-lead plastic DFN
