3 Description

The TPS4H160-Q1 device is fully protected quad-

channel smart high-side switch with four integrated

160-m

Ω 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.
