Si4425DY
Single P-Channel, Logic Level, PowerTrench^TM MOSFET
General Description
This P-Channel Logic Level MOSFET is produced
using Fairchild Semiconductor's advanced PowerTrench
process that has been especially tailored to minimize
the on-state resistance and yet maintain low gate charge
for superior switching performance.
These devices are well suited for notebook computer
applications: load switching and power management,
battery charging circuits, and DC/DC conversion.
Features
-11 A, -30 V. R_DS(ON) = 0.014 Ω @ V_GS = -10 V,
R_DS(ON) = 0.020 Ω @ V_GS = -4.5 V.
Low gate charge (30nC typical).
High performance trench technology for extremely low
R_DS(ON).
High power and current handling capability.
