Product Introduction

Overview

The LTC4365HTS8-1#TRMPBF, manufactured by Analog Devices Inc., is a highly versatile overvoltage, undervoltage, and reverse supply protection controller. This device is designed to protect applications from power supply input voltages that may be too high, too low, or even negative. It achieves this by controlling the gate voltages of external N-channel MOSFETs to ensure the output stays within a safe operating range.

The LTC4365HTS8-1#TRMPBF is particularly suited for applications requiring robust voltage protection, such as in automotive, industrial automation, and portable instrumentation. Its compact 8-lead TSOT-23 package and low operating current make it an ideal choice for space-constrained and power-efficient designs.
