LTC4417IGN#TRPBF

OR Controllers, Ideal Diodes Overview

The LTC4417IGN#TRPBF is a prioritized PowerPath controller manufactured by Analog Devices Inc. It arbitrates between three input supply rails, selecting the highest priority valid supply to power the load. The device operates within an input voltage range of 2.5V to 36V and features a 6V gate driver clamp for external MOSFET protection. It includes fast non-overlapping switching to prevent reverse and cross-conduction currents, while controlled output ramping minimizes inrush current. The part is housed in a 28-lead SSOP package.

OR Controllers, Ideal Diodes Procurement Notes

Verify the specific suffix IGN#TRPBF against the manufacturer datasheet to confirm the industrial temperature range and tape-and-reel packaging configuration. Ensure the design supports the required number of inputs and that external resistor networks correctly set the overvoltage and undervoltage thresholds for each rail. Confirm compatibility with the intended external MOSFET gate drive requirements.

OR Controllers, Ideal Diodes Selection Notes

Select this component when multi-source power redundancy is required with strict priority logic. It is suitable for designs needing wide input voltage coverage up to 36V. Consider the 28-lead SSOP package constraints for PCB layout. Evaluate if cascading multiple units is necessary for more than three input sources, as the device supports daisy-chaining for expanded rail arbitration.

OR Controllers, Ideal Diodes Part Context

This part belongs to the Linear Technology (now Analog Devices) PowerPath family, designed for robust power management. It complements other ideal diode and OR-ing controllers by adding explicit priority arbitration capabilities. The technology focuses on seamless switchover between power sources without interrupting the load, utilizing external MOSFETs for low loss and high efficiency.
