TI TPS7H2140MPWPTSEP

TPS7H2140 - SEP is a fully-protected quad-channel electronic fuse integrating four 160 mΩ NMOS power FETs. Comprehensive diagnostic features and high-accuracy current sensing enable intelligent load control. Externally adjustable current limiting improves overall system reliability by constraining surge or overload currents.
