NDM3000
3 Phase Brushless Motor Driver
General Description
The NDM3000 three phase brushless motor driver consists of
three N-Channel and P-Channel MOSFETs in a half bridge
configuration. These devices are produced using Fairchild's
proprietary, high cell density DMOS technology. This very high
density process is tailored to minimize on-state resistance
which reduces power loss, provide superior switching
performance, and withstand high energy pulses in the
avalanche and commutation modes. These devices are
particularly suited for low voltage 3 phase motor driver such as
disk drive spindle motor control and other half bridge
applications.
