Si6943DQ
Dual P-Channel 2.5V Specified PowerTrench^ MOSFET
General Description
This P-Channel –2.5V specified MOSFET is a rugged
gate version of Fairchild's Semiconductor’s advanced
PowerTrench process. It has been optimized for power
management applications with a wide range of gate
drive voltage (–2.5V to –8V).
Applications
• Load switch
• Motor drive
• DC/DC conversion
• Power management
Features
• –2.5 A, –12 V,
RDS(ON) = 110 mΩ @ VGS = –4.5 V.
RDS(ON) = 180 mΩ @ VGS = –2.5V.
• Extended VGSS range (±8V) for battery applications
• Low gate charge (4.6nC typical)
• High performance trench technology for extremely
low RDS(ON)
• Low profile TSSOP-8 package
