| SI3865BDV New Product Vishay Siliconix Load Switch with Level-Shift PRODUCT SUMMARY VDS2 (V) 1.8 to 8 rDS(on) (W) 0.060 @ VIN = 4.5 V 0.100 @ VIN = 2.5 V 0.175 @ VIN = 1.8 V ID (A) 2.9 2.2 1.7 1.8-V Rated D Low Profile, Small Footprint TSOP-6 Package D 3000-V ESD Protection On Input Switch, VON/OFF D Adjustable Slew-Rate FEATURES D 60-mW Low rDS(on) TrenchFETr D 1.8 to 8-V Input D 1.5 to 8-V Logic Level Control DESCRIPTION The SI3865BDV 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 SI3865BDV operates on supply lines from 1.8 to 8-V, and can drive loads up to 2.9 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: 72848 S-41170--Rev.
