LMD18400 - Quad High Side Driver

The LMD18400 is a fully protected quad high side driver It contains four common-drain DMOS N-channel power switches each capable of switching a continuous 1 Amp load (l3 Amps transient) to a common positive power supply The switches are fully protected from excessive voltage current and temperature
