Texas Instruments TPS1H000-Q1 Smart High-Side Switch

Texas Instruments TPS1H000-Q1 Smart High-Side Switch is a fully protected single-channel high-side power switch with an integrated 1000mΩ NMOS power FET. An adjustable current limit improves system reliability by limiting the inrush or overload current. The high accuracy of the current limit improves overload protection, simplifying the front-stage power design. Besides the current limit, configurable features provide design flexibility in functionality, cost, and thermal dissipation. The device supports full diagnostics with the digital status output. Open-load detection is available in both the ON and OFF states. The Texas Instruments TPS1H000-Q1 supports operation with or without an MCU. Standalone mode allows for the use of the device in isolated systems.
