| SI3861BDV New Product Vishay Siliconix Load Switch with Level-Shift PRODUCT SUMMARY VDS2 (V) 4.5 to 20 FEATURES ID (A) "2.3 "1.9 "1.7 rDS(on) (W) 0.075 @ VIN = 10 V 0.120 @ VIN = 5.0 V 0.145 @ VIN = 4.5 V D D D D D D D 4.5-V Rated ESD Protected: 3000 V 105-mW Low rDS(on) TrenchFETr 4.5 to 20-V Input 1.5 to 8 -V Logic Level Control Low Profile, Small Footprint TSOP-6 Package 3000-V ESD Protection On Input Switch, VON/OFF D Adjustable Slew-Rate RoHS COMPLIANT DESCRIPTION The SI3861BDV includes a p- and n-channel MOSFET in a single TSOP-6 package. The low on-resistance p-channel TrenchFETR 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 Si3861DV operates on supply lines from 4.5 to 20-V, and can drive loads up to 2.3 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: 73343 S-51015--Rev.
