1. V

IN=8V, VON/OFF=8V, TA=25

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%.

FDC6325L Load Switch Application

External Component Recommendation

For Co £ 1uF applications:

First select R2, 100 - 1kW, for Slew Rate control. C1 £ 1000pF can be added in addition to R2 for

further In-rush current control.

Then select R1 such that R1/R2 ratio maintains between 10 - 100. R1 is required to turn Q2 off. For

SPICE simulation, users can download a "FDC6325L.MOD" Spice model from
