| SI1040X New Product Vishay Siliconix Load Switch with Level-Shift PRODUCT SUMMARY VDS2 (V) rDS(on) (W) 0.625 @ VIN = 4.5 V 1.8 to 8 0.890 @ VIN = 2.5 V 1.25 @ VIN = 1.8 V FEATURES ID (A) "0.43 "0.36 "0.3 D D D D D D TrenchFETr Power MOSFET 1.8 to 8-V Input 1.5 to 8-V Logic Level Control Smallest LITTLE FOOTR Package: 1.6 mm x 1.6 mm 2000-V ESD Protection On Input Switch, VON/OFF Adjustable Slew-Rate MARKING CODE Marking Code O WL 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 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. *Minimum R1 value should be at least 10 x R2 to ensure Q1 turn-on. Document Number: 71809 S-20008--Rev.
