LTC4416EMS#PBF

LTC4416EMS#PBF is a Linear Technology/Analog Devices power-path controller that provides automatic, low-loss OR-ing between two DC sources using two external N-channel MOSFETs.
- What it does: Senses two input rails and automatically forwards current from the higher source to the load, while blocking reverse current into the other source. This enables seamless switchover with minimal dropout.
- Protections and behavior: Includes reverse-current protection, per-path current limiting, and fault protection to help prevent source or load damage.
- Packaging: EMS denotes the package type; #PBF indicates Pb-free (RoHS) compliance.
- Typical uses: Redundant or backup power arrangements, two-supply OR-ing (e.g., main/battery, solar + grid, telecom power systems), and other dual-source power routing.
- How to learn more: Refer to the LTC4416 datasheet for exact pinout, electrical specs, recommended external MOSFETs, and application circuits.
If you need, I can summarize the key specs or share a simple schematic.

Here are the key features of LTC4416EMS#PBF:
- Dual high-side ideal-diode/power-path controller for OR-ing two sources to a single load
- Drives two external N-channel MOSFETs to create a low-drop, seamless power path
- Reverse-current protection; prevents backfeeding when sources are off
- Soft-start and inrush control on turn-on
- Cycle-by-cycle current limiting (set by sense resistor) with protection
- Overvoltage and undervoltage protection
- Enable input with fault latch for safe disablement
- Thermal shutdown protection and fault/OK status indicators
- Small 8-pin MSOP (EMS) package; Pb-free (PBF)
Notes: Typical use is hot-swap/OR-ing applications (e.g., redundant or competing sources) with low loss and robust protection.

- Pin count: 16 pins (MSOP-16 package).
- Function: Dual PowerPath/ideal-diode-ORing controller. It drives two external N‑channel MOSFETs to implement high‑efficiency, reverse-current‑protected power-path switching with current limiting for two input sources.

- Manufacturer: Analog Devices, Inc. (ADI). The LTC prefix comes from Linear Technology, which Analog Devices acquired in 2017.
- What kind of company: A global semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing ICs (power management, data converters, amplifiers, sensors, etc.).

Applications for LTC4416EMS#PBF (a power-path controller with ideal-diode behavior, current limit and reverse protection):
- Redundant/ORing power paths: seamless switchover between two supplies to a single load
- Reverse-battery and backfeed protection in automotive and portable systems
- Hot-swap protection for backplanes, boards and telecom/rack equipment
- Battery-backup/UPS and energy-harvesting setups (solar, etc.) with automatic source switching
- General power-path switching in automotive, industrial, telecom and portable devices requiring efficient protection and current limiting

MSOP-10 package (10-lead MSOP, 3×3 mm). The #PBF suffix indicates lead-free RoHS compliant.
