DESCRIPTION
The Si3865CDV 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 Si3865CDV operates on
supply lines from 1.8 to 12 V, and can drive loads up to 2.8 A.

The Si3865CDV 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.
Note:
* Minimum R1 value should be at least 10 x R2 to ensure Q1 turn-on at 1.8 V input.
