Texas Instruments  TPS1H000AQDGNRQ1

The TPS1H000-Q1 device is a fully protected single-channel high-side power switch withan integrated 1000-mΩ NMOS power FET.

An adjustable current limit improves system reliability by limiting the inrush oroverload current. The high accuracy of the current limit improves overload protection, simplifyingthe front-stage power design. Configurable features besides current limit provide designflexibility in the areas of functionality, cost, and thermal dissipation.

The device supports full diagnostics with the digital status output. Open-load detectionis available in both the ON- and OFF-states. The device supports operation with or without an MCU.Standalone mode allows use of the device in isolated systems.
