The TPS1H200A-Q1 device 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. Configurable features besides current limit 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 ON and OFF states. The device supports operation with or without an MCU. Stand-alone mode allows isolated systems to use the device.
