Product Introduction

Overview

The TPS26621DRCR, part of the TPS2662x family from Texas Instruments, is a high-voltage electronic fuse (eFuse) designed to provide comprehensive protection and control for various DC bus voltages. This device operates within a wide supply input range of 4.5 V to 60 V and can withstand both positive and negative supply voltages up to ±60 V. It is particularly suited for systems requiring robust protection against surges, overcurrent, and reverse polarity, making it ideal for industrial and high-reliability applications.
