TPS1H200A-Q1 Description

The TPS1H200A-Q1 device is a fully protected singlechannel high-side power switch with an integrated 200-m? 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 TPS1H200A-Q1 supports full diagnostics with the digital status output. Open-load detection is available in ON and OFF states. The TPS1H200A-Q1  supports operation with or without an MCU. Stand-alone mode allows isolated systems to use the device.
