Data Sheet August 1999 File Number
3.5A, 12V, 0.050 Ohm, Logic Level, Dual
N-Channel LittleFET™ Power MOSFET
This Dual N-Channel powerMOSFETismanufacturedusing
an advanced MegaFET process. This process, which uses
feature sizes approaching those of LSI integrated circuits,
gives optimum utilization of silicon, resulting in outstanding
performance. It is designed for use in applications such as
switching regulators, switching converters, motor drivers,
relay drivers, and low voltage bus switches. This product
achieves full rated conduction at a gate bias in the 3V - 5V
range, thereby facilitating true on-off power control directly
from logic level (5V) integrated circuits.
Formerly developmental type TA49090.
