DESCRIPTION
The Si1040X includes a P- and N-Channel MOSFET in a
single SC89-6 package. The low on-resistance P-Channel
TrenchFET is tailored for use as a load switch. The
N-Channel, with an external resistor, can be used as a
level-shift to drive the P-Channel load-switch. The
N-Channel MOSFET has internal ESD protection and can be
driven by logic signals as low as 1.5 V. The Si1040X
operates on supply lines from 1.8 V to 8 V, and can drive
loads up to 0.43 A.
