Description

The TPS1H000-Q1 device 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. Configurable features besides current limit provide design flexibility in the areas of 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 device supports operation with or without an MCU. Standalone mode allows use of the device in isolated systems.
