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.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
