Abstract

Texas Instruments (TI) high-side power switches are power management devices with integrated protections and diagnostics, designed to drive resistive, capacitive and inductive loads. This portfolio includes high-side switches (integrated-FET), high-side switch controllers (external-FET) and smart eFuse high-side switches (integrated- or external-FET designs with I2T-based wire harness protection). TI offers 12V, 24V and 48V portfolios, tailored to support automotive zone, body and battery management systems, as well as industrial automation and robotics.

Basics of High-Side Switches and Controllers walks through the TI high-side portfolio, outlines comparisons to other power switch designs and explains architectural and application differences. This document also provides an overview of many protection and diagnostic features. Altogether, this document provides a foundational understanding of TI high-side switches, high-side switch controllers and smart eFuse high-side switches.
