P-Channel 1.8V Specified PowerTrench MOSFET
General Description
Features
This P-Channel 1.8V specified MOSFET is a rugged
gate version of Fairchild Semiconductor’s advanced
PowerTrench process. It has been optimized for power
management applications with a wide range of gate
drive voltage (1.8V – 8V).
• –9 A, –12 V.
RDS(ON) = 11 mΩ @ VGS = –4.5 V
RDS(ON) = 14 mΩ @ VGS = –2.5 V
DS(ON) = 20 mΩ @ VGS = –1.8 V
R
• Rds ratings for use with 1.8 V logic
• Low gate charge
Applications
• Load switch
• Motor drive
• DC/DC conversion
• Power management
• High performance trench technology for extremely
low RDS(ON)
• Low profile TSSOP-8 package

Notes:
1. RθJA 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. RθJC is guaranteed by design while RθCA is determined by the user's board design.
