FDG6324L Integrated Load Switch
General Description
This device is intended to be configured as a load switch and is particularly suited for compact computer peripheral switching applications where 3V to 20V input and 0.6A output current capability are needed. This device features a small N-Channel MOSFET (Q1) together with a large P-Channel Power MOSFET (Q2) in a single SC70-6 package.
Features
VDROP =0.2V @ VIN=12V, I L=0.36A. R (ON) = 0.55. VDROP =0.2V @ VIN=5V, I L=0.27A. R (ON) = 0.75. Very small package outline (SC70-6). Control MOSFET (Q1) includes Zener protection for ESD ruggedness (>6KV Human Body Model). High density cell design for extremely low on-resistance.

Notes: 1. Range of Vin can be up to 25V, but R1 and R2 must be scaled such that V GS of Q2 does not exceed -20V. 2. RJA is the sum of the junction-to-case and case-to-ambient thermal resistance where the case thermal reference is defined as the solder mounting surface of the drain pins. RJC is guaranteed by design while RCA is determined by the user's board design. Thermal ratings based on minimum mounting pad. 3. Pulse Test: Pulse Width < 300s, Duty Cycle< 2.0%

External Component Recommendation
For Co 1uF applications: R1 is required to turn Q2 off. R2 and C1 are optional for slew rate control. First select R2, 100 -1K, for slew rate control. Then select R1 such that the ratio R1/R2 is maintained between 10-100. SPICE model (FDG6324L.MOD) available at www.fairchildsemi.com.

SC70-6 Tape and Reel Data and Package Dimensions
SC70-6 Packaging Configuration: Figure 1.0
Customized Label
Packaging Description:
SC70-6 parts are shipped in tape. The carrier tape is made from a dissipative (carbon filled) polycarbonate resin. The cover tape is a multilayer film (Heat Activated Adhesive in nature) primarily composed of polyester film, adhesive layer, sealant, and anti-static sprayed agent. These reeled parts in standard option are shipped with 3,000 units per 7" or 177cm diameter reel. The reels are dark blue in color and is made of polystyrene plastic (antistatic coated). Other option comes in 10,000 units per 13" or 330cm diameter reel. This and some other options are described in the Packaging Information table. These full reels are individually barcode labeled and placed inside a pizza box (illustrated in figure 1.0) made of recyclable corrugated brown paper with a Fairchild logo printing. One pizza box contains three reels maximum. And these pizza boxes are placed inside a barcode labeled shipping box which comes in different sizes depending on the number of parts shipped.
