FDW9926A
Dual N-Channel 2.5V Specified PowerTrench(R) MOSFET
General Description
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 - 10V).
Features
* 4.5 A, 20 V. RDS(ON) = 32 m @ VGS = 4.5 V RDS(ON) = 45 m @ VGS = 2.5 V
* Optimized for use in battery circuit applications * Extended VGSS range (10V) for battery applications * High performance trench technology for extremely low RDS(ON) * Low profile TSSOP-8 package
Applications
* Battery protection * Load switch * Power management

Notes: 1. RJA 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. RJC is guaranteed by design while RCA is determined by the user's board design. a) RJA is 125C/W (steady state) when mounted on a 1 inch copper pad on FR-4.
b) RJA is 208 C/W (steady state) when mounted on a minimum copper pad on FR-4. 2. Pulse Test: Pulse Width < 300s, Duty Cycle < 2.0%
