3 Description

The TPS1H200-Q1 device is a fully protected singlechannel high-side power switch with an integrated

200-mΩ 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.
