A, 04-Mar-02 www.vishay.com 1 Load Switch with Level-Shift PRODUCT SUMMARY VDS2 (V) rDS(on) (W) ID (A) 0.625 @ VIN = 4.5 V "0.43 1.8 to 8 0.890 @ VIN = 2.5 V "0.36 1.25 @ VIN = 1.8 V "0.3 MARKING CODE Marking Code OWL Lot Traceability and Date Code Pin 1 Identifier Part Number Code 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.

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. |
