The TPS2H000-Q1 family is a fully protected dual-channel smart high-side switch, with integrated 1000‑mΩ NMOS power FETs.
Full diagnostics and high-accuracy current-sense features enable intelligent control of the load.
An external adjustable current limit improves reliability of the whole system by limiting the inrush or overload current.
