Overvoltage, Undervoltage Protection PMIC 8-DFN (3x2)
The LTC4365IDDB#TRMPBF is a high-reliability overvoltage, undervoltage, and reverse supply protection controller designed to safeguard sensitive electronic systems from abnormal power conditions. It controls an external N-channel MOSFET to disconnect loads during hazardous voltage events, preventing damage caused by input voltage transients, reverse polarity connections, and supply faults.
This device is widely used in industrial equipment, telecommunications systems, automotive electronics, embedded control platforms, and power distribution applications where robust input power protection is required. The controller offers precise voltage monitoring, adjustable protection thresholds, low operating current, and fast fault response, enabling reliable operation in harsh electrical environments.
