7 DESCRIPTION The Si3865BDV 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 levelshift 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 Si3865BDV operates on supply lines from 1.
8 V to 8 V, and can drive loads up to 2.

5 V, R1 = 20 k COMPONENTS R1 Pull-Up Resistor Typical 10 k to 1 M* R2 Optional Slew-Rate Control Typical 0 to 100 k* C1 Optional Slew-Rate Control Typical 1000 pF * Minimum R1 value should be at least 10 x R2 to ensure Q1 turn-on.
The Si3865BDV 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.
