This document introduces the LTC4413 dual monolithic ideal diode, which helps to reduce the size and improve the performance and reliability of handheld battery-operated devices. The device can automatically select and isolate up to three power sources, such as a wall adapter, an auxiliary supply and a battery. It provides a low loss automatic PowerPath TM management solution for demanding applications that may require short-circuit protection, thermal management and system-level power management and control. The LTC4413 contains two isolated low voltage (2.5V to 5.5V) monolithic ideal diodes. Each ideal diode channel provides a low forward voltage drop (typically as low as 40mV when conducting low current) and a low RDS(ON) (below 100mΩ) when conducting high current—features that are important to extend battery life and reduce heat in portable applications. Furthermore, each channel is capable of providing up to 2.6A of continuous current from a small 3mm × 3mm, 10-pin DFN package. Current-limit and thermal shutdown features further enhance system reliability.
The LTC4413 is a single-chip solution designed to automatically select and isolate up to three power sources, such as a wall adapter, an auxiliary supply (like USB), and a battery. It provides a low-loss automatic PowerPath management solution suitable for applications requiring short-circuit protection and thermal management.
