概述
Description
LTC4352IMS#PBF is a Linear Technology (now Analog Devices) dual MOSFET power-path controller. It forms a low-loss, ideal-diode/OR-ing path between a supply (or two supplies) and a load using two external N-channel MOSFETs, with automatic reverse-current blocking, soft-start, and current-limit protection for hot-swap and redundant power architectures.
Key ideas:
- Drives external FETs to create a protected, lossless power path with reverse-blocking
- Provides current-limiting and inrush/overcurrent control
- Suitable for battery backup, redundant supplies, and power-path OR-ing
Package and suffix:
- IMS denotes the MSOP-8 (small-outline) package option
- #PBF indicates Pb-free, RoHS-compliant manufacturing
Typical use: telecoms, servers, or embedded systems needing safe switchover between power sources without back-feeding.
For exact pinout, electrical specs, and schematic examples, consult the LTC4352 datasheet.

Application
The LTC4352IMS#PBF is a dual power-path controller with hot-swap, current limit, and ideal-diode (OR-ing) protection for two input sources feeding a common load. Typical applications include:
- Redundant power paths and seamless switchover for telecom, data-center, and industrial equipment
- Hot-swap/inrush protection for boards and racks
- Current limiting and short-circuit protection of power rails
- Reverse-current protection to prevent backfeeding between sources
- Automotive/industrial power management with transient protection
- Battery-backup/UPS front ends and energy-harvesting (solar) systems
Designed for reliable, protected dual-source power routing in harsh environments.
