TPS1H000-Q1 Evaluation Module (EVM)
1
Introduction
Texas Instruments TPS1H000-Q1 evaluation module contains a TPS1H000-Q1 integrated circuit (IC),
supporting 1-channel, high-side driver application. The purpose of this EVM is to facilitate evaluation of the
TPS1H000-Q1 for resistive, capacitive, and inductive loads.
1.1
Descriptions
The Texas Instruments TPS1H000-Q1 EVM helps designers evaluate the operation and performance of
the TPS1H000-Q1.
The TPS1H000-Q1 is a fully-protected, high-side switch, with integrated NMOS power FET, and charge
pump. Full diagnostics and high-accuracy current sense features enable intelligent control of the load.
Programmable current-limit function greatly improves the reliability of the whole system.
The TPS1Hxxx-Q1 family is available in different R
DS(on)
values and output current. The device can switch
a wide variety of resistive, inductive, and capacitive loads.
The device diagnostic reporting has two versions to support both digital status output and analog current
sense report. The diagnostics can be disabled for multiplexing the sense pin between different devices.
1.2
Applications
The EVM can be used in the following applications:
•
High-side relay drivers
•
High-voltage power switch for submodule power supply
•
Low-wattage lamp driver
•
General resistive, inductive, and capacitive loads
•
Replace electromechanical relays and fuses
