40-V, 100-mOhm 1-Ch Smart High Side Switch



The TPS1H100-Q1 device is a fully protected high-side power switch, with integrated NMOS power FET and charge pump, targeted for the intelligent control of the variable kinds of resistive, inductive, and capacitive loads. Accurate current sense and programmable current limit features differentiate it from the market.
