Key Features
- Dual-channel ideal diode OR control automatically selects the higher-priority power source with adjustable voltage thresholds for flexible system design
- Low forward voltage drop compared to Schottky diodes reduces power dissipation in high-current redundant power paths
- Adjustable threshold pins allow fine-tuning of switchover voltage levels from approximately 2.5 V to 5.5 V input range
- Compact 16-pin DFN (3 mm x 5 mm) package minimizes PCB footprint in space-constrained power supply modules
- Automatic switchover with no glitch on output enables uninterrupted operation during power source transitions in telecom and server applications
Applications
The LTC4415IDHC#TRPBF is ideal for redundant power supply architectures in servers, telecommunications equipment, and industrial controllers where seamless failover between two DC power rails — such as a main 5 V supply and a backup battery — is required without interruption to the load. Its adjustable threshold inputs allow the designer to set precise switchover points for systems with input rails ranging from 2.5 V to 5.5 V, accommodating a wide range of battery backup and OR-ing applications. The compact DFN-16 package and integrated gate drive simplify PCB design in rack-mounted network equipment and embedded computing platforms.

Frequently Asked Questions
How many power input channels does the LTC4415IDHC#TRPBF support and what voltage range does it handle?
The LTC4415IDHC#TRPBF supports 2 independent input channels and is designed for power rail voltages in the range of 2.5 V to 5.5 V, making it suitable for dual-supply OR-ing in low-voltage server, networking, and embedded systems where seamless switchover between power sources is critical.
What advantage does the LTC4415IDHC#TRPBF offer over a discrete Schottky diode OR-ing circuit?
Unlike discrete Schottky diodes that introduce a 0.3 V to 0.7 V forward voltage drop at load currents above 1 A, the LTC4415IDHC#TRPBF uses active MOSFET-based ideal diode control to achieve a much lower forward voltage drop — typically under 20 mV — significantly reducing power dissipation and heat generation in redundant power systems.
How does the adjustable threshold feature of the LTC4415IDHC#TRPBF benefit a battery backup design?
The adjustable threshold pins allow the designer to program the exact input voltage at which the LTC4415 switches from the primary supply to the backup battery, ensuring that switchover occurs at a controlled voltage level such as 4.5 V rather than allowing the system to brown out, improving reliability in 5 V backup supply designs with lithium-ion or lead-acid batteries.
What is the package type and size of the LTC4415IDHC#TRPBF, and how does it affect board layout for power modules?
The LTC4415IDHC#TRPBF is housed in a 16-pin DFN (R-PDSO-N16) measuring 3 mm x 5 mm with an exposed thermal pad, enabling compact placement on high-density power boards. The small footprint and low package height make it well-suited for 1U rack-mount power modules where PCB area is limited to under 10 cm².
