LTC4416IMS-1#PBF

OR Controllers, Ideal Diodes Overview

The LTC4416IMS-1#PBF is a dual-channel PowerPath controller manufactured by Analog Devices Inc., designed for efficient power source selection and switching. It operates within a supply voltage range of 3.6V to 36V and supports a working temperature range from -40°C to 85°C. The device features a 10-MSOP package with a typical operating supply current of 130 µA. Key timing specifications include a turn-on delay of 60 µs and a turn-off delay of 30 µs. It utilizes P-channel MOSFETs for low-loss ideal diode emulation, enabling seamless ORing of multiple power sources.

OR Controllers, Ideal Diodes Feature Summary

• Provides near-ideal diode functionality for two independent power sources using external P-channel MOSFETs.
• Integrates soft-switching control to prevent output voltage droop during transitions between power sources.
• Features fast turn-on and fast turn-off capabilities that activate when input voltage differences exceed 25mV.
• Includes internal gate driver voltage clamping to protect connected MOSFETs from overvoltage conditions.

OR Controllers, Ideal Diodes Applications

• Battery backup systems requiring automatic switchover to auxiliary power
• Industrial and automotive applications involving high-current power path switching
• Uninterruptible power supply (UPS) circuits
• Logic-controlled power switches with redundant power inputs

OR Controllers, Ideal Diodes Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS3 status as documented in official Analog Devices materials. Confirm the 10-MSOP package dimensions and pinout against the latest datasheet revision. Ensure the operating environment remains within the specified -40°C to 85°C range. Check for any product change notifications regarding epoxy or marking changes that may affect assembly processes.

OR Controllers, Ideal Diodes Selection Notes

Select this component when dual-channel power ORing with minimal quiescent current is required. The wide 3.6V to 36V input range accommodates various battery configurations, including up to eight series-connected lithium-ion cells. Consider the 130 µA supply current and 35 µA per channel static current for low-power designs. The integrated soft-switching feature makes it suitable for sensitive loads where voltage transients must be minimized during source transitions.

OR Controllers, Ideal Diodes Part Context

This part belongs to the PowerPath family of controllers from Analog Devices. It is closely related to the standard LTC4416, with the -1 variant offering specific enable pin configurations for controlled fast turn-off of secondary channels. The device simplifies power management by replacing traditional diode ORing circuits, thereby reducing heat generation and extending battery life in portable and industrial equipment.

OR Controllers, Ideal Diodes Replacement Considerations

LTC4416EMS-1#PBF is a direct equivalent within the same series, differing primarily in package type (TSSOP vs MSOP). Verify pin compatibility and thermal performance if substituting packages. No other cross-model replacements are confirmed in public documentation without additional engineering validation.
