Product Overview: LTC4417IGN#PBF

The LTC4417IGN#PBF from Linear Technology is a prioritized power path controller designed to manage multiple power sources in a system. This integrated circuit ensures that the most reliable power source is connected to the load while providing a seamless transition between sources when necessary. Its primary application is in systems where continuous power is critical, and it excels in environments where power sources may vary in availability or reliability.

The LTC4417IGN#PBF can control up to three power paths, making it versatile for various applications, including portable devices, automotive systems, industrial equipment, and servers. It automatically selects the highest priority valid power source, based on user-defined priorities, and quickly switches to the next available source without interrupting the supply to the load.

This product comes in a narrow 16-lead SSOP package, which is suitable for space-constrained applications. The LTC4417IGN#PBF operates over a wide voltage range, accommodating supplies from 2.5V to 36V, and is capable of withstanding up to 42V of transient overvoltages, making it robust against power spikes.

One of the key features of the LTC4417IGN#PBF is its low quiescent current, which is crucial for battery-powered applications where power efficiency is a priority. Additionally, it offers an adjustable undervoltage lockout for each input, ensuring that only sources with sufficient voltage are considered valid, thus protecting the load from brownout conditions.

Other notable features include an onboard 1.5% accurate reference, a PowerFail output, and a status output for each channel, which provides real-time feedback on the state of each power path. The LTC4417IGN#PBF also includes reverse input protection to prevent damage in case of reverse supply connection, enhancing the overall durability and reliability of the system it is integrated into.

In summary, the LTC4417IGN#PBF from Linear Technology is a sophisticated solution for managing multiple power sources in a wide range of applications. Its ability to prioritize power sources, coupled with its robust feature set, ensures that your system remains powered in the most efficient and reliable manner possible.
