F77A N-Channel Logic Level PowerTrench MOFET January F77A General escription This N-Channel Logic Level MOFET is produced using Fairchild emiconductor s advanced PowerTrench process that has been especially tailored to minimize on-state resistance and yet maintain superior switching performance. These devices are well suited for low voltage and battery powered applications where low in-line power loss and fast switching are required. Applications C/C converter Load switch Motor drives Features 5 A, 3 V. R (ON) = 5.5 mω @ V G = V R (ON) = mω @ V G = 4.5 V. Low gate charge (37nC typical) Fast switching speed. High performance trench technology for extremely low R (ON). High power and current handling capability. 5 4 3 O- G 7 Absolute Maximum Ratings T A=5 o C unless otherwise noted ymbol Parameter Ratings Units V rain-ource Voltage 3 V V G Gate-ource Voltage ± V I rain Current Continuous (Note a) 5 A P Pulsed Power issipation for ingle Operation (Note a).5 (Note b).
