Applications
LTC4091EDJC#TRPBF is used in industrial equipment, telecom infrastructure, and smart meters that require a battery backup path to maintain operation during AC power interruptions. Its 36 V input rating accommodates higher-voltage power supply rails common in 24 V to 36 V industrial systems, and the integrated power path manager enables seamless switchover between the main supply and the backup battery. It also suits building automation controllers, gateway devices, and medical instruments where uninterrupted power delivery during brief outages is critical.

Frequently Asked Questions
What is the maximum input voltage LTC4091EDJC#TRPBF supports for industrial battery backup designs?
LTC4091EDJC#TRPBF supports input voltages up to 36 V, which covers 24 V and 36 V industrial power supply rails common in factory automation, telecom base station equipment, and smart grid meters requiring reliable backup battery management above the typical 5 V or 12 V consumer range.
How does the power backup manager function in LTC4091EDJC#TRPBF differ from a standalone charger IC?
Unlike a standalone charger, LTC4091EDJC#TRPBF combines a linear battery charger with a power path manager that automatically switches the system load to the backup battery when the main 36 V input drops or fails. This seamless failover protects system operation without additional external switching logic or a separate power mux IC.
Can the charge voltage threshold of LTC4091EDJC#TRPBF be adjusted for different battery capacities?
Yes. LTC4091EDJC#TRPBF includes adjustable threshold functionality, allowing designers to set the charge termination voltage and charge current via external resistors. This flexibility supports different Li-ion or Li-polymer cell configurations with varying capacity and voltage requirements within the 36 V maximum input rating.
What is the package and pin count of LTC4091EDJC#TRPBF and how does it affect PCB density?
LTC4091EDJC#TRPBF comes in a 22-pin plastic DFN package (JESD-30 R-PDSO-N22). The DFN form factor has a smaller footprint than an equivalent SOIC-22 or DIP package, enabling compact PCB layouts in space-constrained industrial control boards while providing sufficient pins for the charger and power management signal connections.
