The TPS27S100x is a single-channel, fully-protected, high-side switch with an integratedNMOS and charge pump. Full diagnostics and high-accuracy current-monitor features enableintelligent control of the load. An adjustable current-limit function greatly improves thereliability of the whole system. The device diagnostic reporting has two versions to support bothdigital fault status and analog current monitor output. Accurate current monitor and adjustablecurrent limit features differentiate it from the market.
