Descripción general

Description

The LTC4417CUF#TRPBF is a dual power-path controller from Linear Technology (now Analog Devices) used to implement ideal-diode ORing and reverse-current protection between two input rails and a single load. It drives two external N-channel MOSFETs to create low-loss power paths, automatically selecting the active input (typically the higher voltage) and preventing backflow into the inactive rail. It offers soft-start, current limit, undervoltage lockout, and thermal protection for robust operation. Typical applications include redundant or hot-swappable power supplies, battery-backed rails, and any system needing seamless, high-efficiency power-path switching.
Packaging note: LTC4417CUF#TRPBF denotes the CUF package variant, supplied in Tape-and-Reel Pb-free. The #TRPBF suffix indicates tape-and-reel packaging with Pb-free finish. For exact pinout, electrical specs, and MOSFET recommendations, consult the LTC/ADI datasheet.

Package

8-lead MSOP package (3x3 mm). Pb-free and supplied in Tape-and- Reel (TRPBF).

Pinout

- Pin count: 8 pins (8-pin MSOP/SOIC style, as in CUF package)
- Function: Power-path/ideal-diode controller. It manages two input sources to a load, driving an external MOSFET to provide low-drop, reverse-current protection and basic current-limit protection for efficient OR-ing of supplies.

Manufacturer

Manufacturer: Analog Devices, Inc. (ADI). It is a global semiconductor company that designs and manufactures analog, mixed-signal, and power-management integrated circuits. The LTC prefix comes from Linear Technology, whose product line is now part of Analog Devices after the acquisition.

Application

Application areas include dual-supply ideal-diode OR-ing and reverse-current protection for hot-swappable or redundant power rails; power-path management in telecom, data centers, automotive, and industrial equipment; battery backup/UPS and solar-battery systems; and any circuit requiring seamless, low-loss switchover between two DC sources.
