Notes:
1. Range of V
in
can be up to 25V, but R
1
and R
2
must be scaled such that V
GS
of Q2 does not exceed -20V.
2. R
θ
JA
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. R
θ
JC
is
guaranteed by design while R
θ
CA
is determined by the user's board design. Thermal ratings based on minimum mounting pad.
3. Pulse Test: Pulse Width < 300μs, Duty Cycle < 2.0%
FDG6324L Load Switch Application
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.
