LTC4415EMSE#TRPBF

The LTC4415EMSE#TRPBF by Analog Devices / Maxim Integrated is a dual PowerPath ideal diode controller designed for high current applications. Each of the two monolithic ideal diodes can supply up to 4A with a typical forward conduction resistance of only 50mΩ. The device operates over a wide voltage range of 1.7V to 5.5V, with a regulated diode voltage drop of 15mV at low currents, which helps extend power supply operating range and ensures smooth switchover.

The current limit for each diode is independently adjustable from 0.5A to 4A using external resistors on the CLIM pins, and the ideal diode currents can be monitored via CLIM pin voltages. The LTC4415 features precision enable thresholds for prioritized power supply ORing and includes soft-start to limit inrush current. Open-drain status pins indicate forward conduction, while warning pins signal when the die temperature approaches thermal shutdown or if the output load exceeds the current limit threshold.

This component is supplied in a 16-lead MSOP-EP (Exposed Pad) package, suitable for surface mounting. Its features make it well-suited for applications such as prioritized power supply ORing, battery and wall adapter diode ORing, backup battery diode ORing, supercapacitor ORing, and multiple battery sharing scenarios.
