Applications
The LTC4412HS6#TRMPBF is used in battery-powered portable devices such as laptops, medical instruments, and handheld test equipment where seamless transition between a DC adapter and a lithium battery is required. Its automatic PowerPath algorithm selects the higher-voltage supply without glitches, enabling continuous operation during plug-in events without CPU involvement. Industrial UPS modules and wearable medical monitors also use this IC to prioritize wall power when available and switch instantly to battery backup when the primary source fails.

Frequently Asked Questions
How does the LTC4412HS6#TRMPBF select between two power sources without causing output voltage glitches?
The LTC4412HS6#TRMPBF monitors both input rails and drives an external P-channel MOSFET to connect the higher-voltage source to the output in under 1 µs, preventing the output from drooping below the operating threshold of downstream loads. This glitch-free switchover is achieved without a microcontroller, relying on the IC's internal comparator and gate drive circuit to maintain continuous power delivery during transitions between a 5 V adapter and a 3.7 V lithium battery.
What supply voltage range does the LTC4412HS6#TRMPBF support and how does this affect its use in multi-chemistry battery designs?
The LTC4412HS6#TRMPBF operates across supply voltages from 2.5 V to 28 V, covering single-cell lithium-ion (3.0 V to 4.2 V), two-cell lithium (6 V to 8.4 V), and lead-acid (10 V to 14 V) chemistries within one design. This wide input range eliminates the need for separate power management ICs in multi-chemistry product platforms, reducing BOM count by at least 2 components per power path.
Why is the 6-pin ThinSOT package of the LTC4412HS6#TRMPBF advantageous for portable medical device designs?
The 6-pin ThinSOT package occupies approximately 8.1 mm² of PCB area with a 1 mm height profile, fitting within the tight board constraints of glucose monitors, hearing aids, and wearable ECG patches where overall device thickness must remain below 5 mm. At this footprint, the LTC4412HS6#TRMPBF requires no heatsinking for load currents up to 500 mA, simplifying thermal management in sealed plastic enclosures.
How does using an external P-channel MOSFET with the LTC4412HS6#TRMPBF benefit designs needing more than 1 A of load current?
Because the LTC4412HS6#TRMPBF drives an external FET gate rather than integrating the switch, designers can select a P-channel MOSFET with RDS(on) as low as 5 mΩ to handle 5 A or more, limited only by the chosen FET's ratings. This architecture allows a single LTC4412HS6#TRMPBF to scale from a 100 mA IoT sensor application to a 3 A industrial power bank by simply swapping the external FET, reusing the same PCB layout.
