5 to 8-V Logic Level Control DESCRIPTION The Si3863DV 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 Si3863DV operates on supply lines from 2.
5 to 12-V, and can drive loads up to 2.
5 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.
