TPS1H200A-Q1 Smart High-Side Switch Texas Instruments TPS1H200A-Q1 Single-Channel Smart High-Side Switch is a fully protected single-channel high-side power switch with an integrated 200mΩ 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.
