概要

Description

LTC4352IMS#PBF is Linear Technology’s (Analog Devices) single‑channel hot‑swap controller with reverse‑current protection and current limiting for a high‑side MOSFET. It controls an external N‑channel MOSFET to safely power up/down a rail, provides inrush/current limiting, blocks reverse current when the source is off or another supply is present, and protects the rail from overcurrent and thermal faults. It uses a sense resistor to set the current limit and includes undervoltage protection. The package IMS denotes the MSOP‑10 form factor, and #PBF indicates RoHS-compliant, lead‑free packaging.
Typical use: protect and manage a power rail in servers, telecom equipment, or battery-backup paths, enabling ideal‑diode ORing and controlled hot‑swap of a supply.

Features

LTC4352IMS#PBF features (concise):
- Dual hot-swap controllers in one package (drives two N-channel FETs)
- Independent programmable current-limit for each channel
- Slew-rate controlled soft-start to limit inrush
- Reverse-battery protection and input overvoltage protection
- Short-circuit protection with fault indication
- Undervoltage lockout and thermal protection
- Fault/Status reporting per channel (open-drain outputs)
- Enable/disable control for each channel
- Suitable for dual supply hot-swap, power-path ORing, and back-up paths
- Small IMS(MSOP) package, lead-free PBF version

Package

8‑lead MSOP package (MSOP‑8), plastic, Pb‑free (PBF).

Pinout

- Pin count: 8 pins (MSOP-8 package, code IMS).
- Function: LTC4352IMS#PBF is a dual hot-swap/power-path controller that drives two external MOSFETs to implement ideal-diode/OR-ing between two input sources to a common output, with programmable current limit, soft-start, and protection against reverse current and short-circuit.

Manufacturer

Manufacturer: Analog Devices, Inc. (the LTC4352 was originally from Linear Technology, which is now part of Analog Devices).
What kind of company: Analog Devices is a multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing integrated circuits.

Application

Common application areas for LTC4352IMS#PBF:
- Seamless switchover between primary supply and backup (battery or supercapacitor) in microcontrollers, memory, and RTC applications.
- Redundant power paths with ideal-diode OR-ing for telecom, data-center, automotive, and industrial equipment.
- Hot-swap protection and reverse-current/isolation in two-supply systems.
- General backup power management where reliable, fast switching and controlled current are required.
