Notes:
1. 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. RqJA 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.
RqJC is guaranteed by design while RqCA is determined by the user's board design.
3. Pulse Test: Pulse Width < 300µs, Duty Cycle < 2.0%

External Component Recommendation
R1 is required to turn Q2 off.
R2 is optional for Slew Rate Control.
For Co £ 1uF applications:
First select R2,100 - 1KW, for Slew Rate control.
Then select R1 such that R1/R2 ratio maintains between 10 - 100.
