November 1998 FDC6329L Integrated Load Switch General Description This device is particularly suited for compact power management in portable electronic equipment where 2.5V to 8V input and 2.5A output current capability are needed. This load switch integrates a small N-Channel power MOSFET (Q1) which drives a large P-Channel power MOSFET (Q2) in one tiny SuperSOTTM-6 package. Features VDROP=0.2V @ VIN=5V, IL=2.8A. R(ON) = 0.07Ω VDROP=0.2V @ VIN=2.5V, IL=1.9A. R(ON) = 0.105Ω. Control MOSFET (Q1) includes Zener protection for ESD ruggedness (>6KV Human Body Model). High performance trench technology for extremely low on-resistance. SuperSOTTM-6 package design using copper lead frame for superior thermal and electrical capabilities.

Range of Vin can be up to 8V, but R1 and R2 must be scaled such that VGS of Q2 does not exceed -8V. 2. RθJA 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. RθJC is guaranteed by design while RθCA is determined by the user's board design. 3. Pulse Test: Pulse Width < 300µs, Duty Cycle < 2.0%. FDC6329L Load Switch Application External Component Recommendation: For applications where Co ≤ 1µF. For slew rate control, select R2 in the range of 1k - 4.7kΩ . For additional in-rush current control, C1 ≤ 1000pF can be added. Select R1 so that the R1/R2 ratio ranges from 10 - 100. R1 is required to turn Q2 off.
