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.

The Si1040X is ideally suited for high-side load switching in portable applications. The integrated N-Channel level-shift device saves space by reducing external components. The slew rate is set externally so that rise-times can be tailored to different load types.
Notes: a. Minimum R1 value should be at least 10 x R2 to ensure Q1 turnon.
