概述

Description

The LTC4412ES6#TRMPBF is a low-loss PowerPath controller designed to manage power flow in battery-powered and dual power source systems. It enables seamless switching between power sources, ensuring continuous operation and extending battery life. The component is housed in a compact SOT-23 package and features a low operating current, enhancing power efficiency.
Key features include a wide input voltage range, low dropout voltage, and low quiescent current. It provides reverse battery and reverse current protection, safeguarding the system against potential damage. The device is ideally suited for applications like battery backup systems, uninterruptible power supplies, and portable electronics.
The LTC4412ES6#TRMPBF operates by controlling an external P-channel MOSFET, minimizing voltage drop and power dissipation compared to diode-based solutions. This low-loss characteristic makes it an efficient choice for maintaining battery longevity and performance in devices where power efficiency is crucial.

Features

The LTC4412ES6#TRMPBF is a low-loss PowerPath controller designed for automatic switching between two power sources. It features a low quiescent current and controls an external P-channel MOSFET to prevent reverse current flow, ensuring efficient power management. With a wide operating voltage range from 2.5V to 28V, it is suitable for various applications, including battery-powered and portable devices. The device offers fast switching, typically within 1.5ms, to ensure minimal disruption when changing power sources.
Its key features include a low dropout voltage, reverse battery protection, and the ability to prioritize the main power source. The LTC4412ES6#TRMPBF also offers thermal shutdown protection, enhancing system reliability. The device is available in a compact 6-lead TSOT-23 package, making it suitable for space-constrained applications. The "ES6" indicates the package type, and the "#TRMPBF" suffix denotes a tape and reel packaging for automated manufacturing processes, as well as RoHS-compliance with lead-free (Pb-free) construction.

Package

The LTC4412ES6#TRMPBF is a power prioritizer in a SOT-23-6 package. It efficiently manages power sources by seamlessly switching between them, ensuring uninterrupted power delivery.

Pinout
