2.3.6 TPS4H160-Q1

The TPS4H160-Q1 device is fully protected quad-channel smart high-side switch with four integrated 160-mΩ NMOS power field-effect transistors (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.
