Fairchild FDW2503N Dual n-channel 2.5v specified powertrench mosfet Datasheet

FDW2503N
Dual N-Channel 2.5V Specified PowerTrench MOSFET
General Description
Features
This N-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 – 12V).
• 5.5 A, 20 V.
• Extended VGSS range (±12V) for battery applications
Applications
• Low gate charge
• Load switch
• High performance trench technology for extremely
low RDS(ON)
• Motor drive
• DC/DC conversion
RDS(ON) = 0.021 Ω @ VGS = 4.5 V
RDS(ON) = 0.035 Ω @ VGS = 2.5 V
• Low profile TSSOP-8 package
• Power management

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.
a) RθJA is 125°C/W (steady state) when mounted on a 1 inch² copper pad on FR-4.
b) RθJA is 208°C/W (steady state) when mounted on a minimum copper pad on FR-4.
2. Pulse Test: Pulse Width < 300µs, Duty Cycle < 2.0%
