The Si3865DV includes a p- and n-channel MOSFET in a
single TSOP-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 Si3865DV operates on
supply lines from 1.8 to 8-V, and can drive loads up to 2.7 A.

The Si3865DV 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.
*Minimum R1 value should be at least 10 x R2 to ensure Q1 turn-on.
