The 2SK681A, N-channel vertical type MOS FET, is a switching device which can be driven directly by the output of ICs having a 5 V power source. The MOS FET has excellent switching characteristic and is suitable for use as a high-speed switching device in digital circuits.
DESCRIPTION The µ PA1981 is a N-channel/P-Channel MOS FET pair for compact power management in portable electronic equipment where 2.5 to 8 V input and 2.8 A output current capability are needed. This load switch integrated a small N-channel MOS FET (Q1), which drives a large P-Channel MOS FET (Q2) in one tiny package (SC-95).
