DESCRIPTION
The Si1867DL 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-

APPLICATIONS
? Load Switch with Level-Shift for Portable Applications
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 Si1867DL operates on
supply lines from 1.8 V to 8 V, and can drive loads up to 0.6 A.

portable applications. The integrated n-channel level-shift
devices 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 least 10 x R2 to ensure Q1 turn-on.
