LTC4365IDDB

LTC4365IDDB Description

The LTC4365IDDB by Analog Devices Inc. is a specialized power management IC designed for robust overvoltage (OV) and undervoltage (UV) protection in electronic systems. Operating within a 2.5V to 34V supply range, it ensures reliable power conditioning for sensitive circuits. With a low 125µA supply current, it minimizes power overhead while delivering precise voltage monitoring. Packaged in a surface-mount tube, this obsolete (ECCN: OBSOLETE) component remains relevant for legacy designs requiring high-voltage tolerance and stability. Its Moisture Sensitivity Level (MSL) 1 rating ensures durability in varied environmental conditions.
