LTC4041EUFD in Linear Tech / ADI LT Series Family
The LTC4041EUFD family, manufactured by Analog Devices (formerly Linear Technology), is a sophisticated backup power management solution designed to provide uninterruptible power from a supercapacitor source. This PMIC integrates a 2.5A buck battery charger and a high-current step-up DC/DC converter, making it ideal for systems that require high reliability during sudden input power loss. It manages charging, monitoring, and power path switching automatically to ensure data integrity and system stability in critical embedded environments.
Variants in This Sub-Family
Variants within the LTC4041 sub-family are primarily distinguished by their packaging options and temperature grading. While the EUFD designation specifically refers to the 24-lead QFN package with an enhanced thermal pad, industrial grade (I-grade) and extended temperature (E-grade) versions provide different operating ranges. Some variants may also differ in their factory-set threshold voltages or lead-free finish status, though the core PMIC architecture remains consistent across the series.
