Smart high-side switch improves system reliability

Texas Instruments TPS1H200A-Q1 Single-Channel Smart High-Side Switch is a fully protected single-channel high-side power switch with an integrated 200mOhm NMOS power FET. An adjustable current limit improves system reliability by restricting the inrush or overload current. The high accuracy of the current limit increases overload protection, simplifying the front-stage power design. Configurable features besides current limit offer design flexibility in cost, functionality, and thermal dissipation. The device supports full diagnostics with the digital status output. Open-load detection is available in ON and OFF states. The device supports operation with or without an MCU. The stand-alone mode allows isolated systems to use the device. Applications include Body lighting, infotainment system, ADAS, single-channel high-side switch for submodules, and general resistive, inductive and capacitive loads.
