The purpose of this EVM is to facilitate evaluation of the TPS1H100-Q1 for resistive, capacitive, and inductive loads. 1.1 Descriptions The Texas Instruments TPS1H100-Q1 EVM helps designers evaluate the operation and performance of the TPS1H100-Q1. The TPS1H100-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 whole system’s reliability. TPS1Hxxx-Q1 family is available in different Rdson 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 • • • • • 1.3 Features • • • • • • • • 2 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 Single-channel high-side power switch, tested according to AECQ100-12 Operating voltage 5 to 40 V, extended operating down to 3.5 V Operating junction temperature: –40ºC to 150ºC Very-low standby current:
