General Description
Very small package outline (SC70-6).
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
Control MOSFET (Q1) includes Zener protection for ESD
ruggedness (> 6KV Human Body Model).
High density cell design for extremely low on-resistance.
N-Channel MOSFET (Q1) together with
a large P-Channel
Power MOSFET (Q2) in a single SC70-6 package.

Notes:
1. Range of Vin can be up to 25V, but R1 and R2 must be scaled such that VGS of Q2 does not exceed -20V.
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. Thermal ratings based on minimum mounting pad.

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 -1KW, for slew rate control.
Then select R1 such that the ratio R1/R2 is maintained between 10-100.
