3 Description
The TPS4H160-Q1 device is fully protected quad-
channel smart high-side switch with four integrated
160-mΩ NMOS power FETs.
Full diagnostics and high-accuracy current sense
enable intelligent control of the load.
An external adjustable current limit improves the
reliability of whole system by limiting the inrush or
overload current.
