Description：

The TPS1H000-Q1 device is a fully protected single‑channel high‑side power switch with an integrated 1000‑mΩ NMOS power FET. The adjustable current limit improves system reliability by limiting inrush or overload currents. High‑accuracy current limiting enhances overload protection, simplifying front‑end power supply design. Configurable features provide design flexibility in terms of functionality, cost, and thermal dissipation. The device supports comprehensive diagnostics via a digital status output. Open‑load detection is available in both on‑state and off‑state conditions. The device can operate with or without an MCU. The "stand‑alone" mode enables the use of this device in isolated systems.
