linear DESIGN FEATURES LTJournal-V21N1-02-df-LTC436x-Kevin_Wong service manual

About this manual

This document describes the LTC4360, LTC4361, and LTC4362 devices designed to protect mobile devices from hot-plug transients and incorrect power adapters. The parts control an external N-channel MOSFET or incorporate an internal one to block overvoltage conditions up to 85V at the input.

Frequently asked questions

What is the maximum input voltage these controllers can withstand?

The LTC4360 and LTC4361 can withstand up to 85V at IN, SENSE, and GATEP.

What is the overvoltage threshold for these devices?

All three parts have an accurate overvoltage threshold of 5.8V.

How long does the initial delay cycle last when power is first applied?

A 130ms delay cycle starts to isolate the output from input transients at startup.
