3 Description
The TPS1H000-Q1 device is a fully protected single-
channel high-side power switch with an integrated
1000-mΩ NMOS power FET.
An external adjustable current limit improves the
reliability of the whole system by limiting the inrush or
overload current. Highly accurate limit values save
the front-stage power budget. Configurable behaviors
after current limit provide design flexibility,
considering the functionality, cost, and thermal
dissipation.
The device supports full diagnostics with the digital
status output. Highly accurate and low-threshold
open-load detection enables real-time on-state
monitoring. The device supports operation with an
MCU, or without one in the standalone mode, which
allows the system to implement the full functionality
locally.
