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 to 8 V, and can drive loads up to 0.43 A.
