The low on-resistance p-channel TrenchFET is tailored for use as a load Switch .
2 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 V. The Si3865 DDV operates on supply lines from V to 12 V, and can drive loads up to CIRCUITSN otea. Minimum R1 value should be at least 10 x R2 to ensure Q1 turn-on The Si3865 DDV 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.

9 I, 18-Dec-06 DWG: 5540 AN823 vishay SiliconixDocument Number: LITTLE FOOTR TSOP-6 Power MOSFETsSurface mounted power MOSFET packaging has been based onintegrated circuit and small signal packages. Those packageshave been modified to provide the improvements in heat transferrequired by power MOSFETs. Leadframe materials and design,molding compounds, and die attach materials have beenchanged. What has remained the same is the footprint of basis of the pad design for surface mounted power MOSFETis the basic footprint for the package. For the TSOP-6 packageoutline drawing see and for the minimum pad converting the footprint to the pad set for a power MOSFET, youmust remember that not only do you want to make electricalconnection to the package, but you must made thermal connectionand provide a means to draw heat from the package, and move itaway from the the case of the TSOP-6 package, the electrical connections arevery simple.
10 Pins 1, 2, 5, and 6 are the drain of the MOSFET andare connected together. For a small signal device or integratedcircuit, typical connections would be made with traces that inches wide. Since the drain pins serve the additionalfunction of providing the thermal connection to the package, thislevel of connection is inadequate. The total cross section of thecopper may be adequate to carry the current required for theapplication, but it presents a large thermal impedance. Also, heatspreads in a circular fashion from the heat source. In this case thedrain pins are the heat sources when looking at heat spread on thePC 1 shows the copper spreading recommended footprint forthe TSOP-6 package. This pattern shows the starting point forutilizing the board area available for the heat spreading copper.
