LMD18400 Quad High Side Driver
General Description
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 An instantaneous power sensing circuit calculates the product of the
voltage across and the current through each DMOS switch and limits the power to a safe level The device can be disabled to produce a ‘‘sleep’’ condition reducing the supply current to less than 10 mA Separate ON OFF control of each switc...
