DESCRIPTION
The Si1865DDL includes a p- and n-channel MOSFET in
a single SC70-6 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 Si1865DDL operates
on supply lines from 1.8 V to 12 V, and can drive loads up to
1.1 A.

Note:
a. Minimum R1 value should be at least 10 x R2 to ensure Q1 turn-on.
The Si1865DDL 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.
