11.12 FDC642P

FDC642P is a p-channel mosfet which is used for switching the panel supply.

General Description

This P-channel 2.5V specified MOSFET is produced using advanced PowerTrench process
that has been especially tailored to minimize on state resistance and yet maintain low gate
charge for superior switching performance.

These devices have been design to offer exceptional power dissipation in a very small
footprint for applications where larger packages are impractical.

Features



Fast switching speed.



-4 A,-20V.

RDS(on)

= 0.065 ohm @ V

GS

=-4.5V

R

DS(on)

= 0.100 ohm @ V

GS

=-2.5V



Low gate charge (7.2nC typical).



High performance trench technology for extremely low R

DS(on)



SuperSOT-6 package:small footprint (72% smaller than Standard SO-8;low profile
(1mm thick).
