TPS2H160-Q1 Evaluation Module (EVM) Copyright © 2016, Texas Instruments Incorporated 10 1 Introduction 1 www.ti.com Introduction Texas Instruments' TPS2H160-Q1 evaluation module contains a TPS2H160-Q1 integrated circuit (IC), supporting dual-channel high-side switch application. The purpose of this EVM is to facilitate evaluation of the TPS2H160-Q1 for resistive, capacitive, and inductive load. 1.1 Descriptions The TPS2H160-Q1 family is a fully protected dual-channel high-side power switch, with integrated NMOS power FET and charge pump. Full diagnostics and high-accuracy current-sense features enable intelligent control of the load. The device diagnostic reporting has two versions to support both digital status output and analog current sense reports. The diagnostics can be disabled for multiplexing the sense pin between different devices. Thermal shutdown behaviors as latch off or auto-retry are internally fixed in the part. External programmable current limit improves the reliability of the system by limiting the inrush or overload current. 1.2 Applications The device can be used in the following applications: • Multi-channel LED drivers, bulb drivers • Multi-channel high-side power switches • Multi-channel high-side relay drivers 1.3 Features This EVM supports the following features: • Operating voltage of 3.4–40 V • Operating junction temperature: –40°C to 150°C • Highly accurate current sense • Adjustable current limit with external resistor • Multiplex high accuracy current sense or ST report • Tested according to AECQ100-12 • Certification of ISO7637-2 and ISO16750-2 2 TPS2H160-Q1 Evaluation Module (EVM) Copyright © 2016, Texas Instruments Incorporated SLVUAS9 – August 2016 Submit Documentation Feedback TPS2H160-Q1 Schematic www.ti.com 2 TPS2H160-Q1 Schematic Figure 1 illustrates the EVM schematic.
