BD63242EFV
General Description
BD63242EFV is a 1chip driver composed of a Power
DMOS FET Motor Driver. It features a sensor-less drive
which does not require a hall device as a position
detection sensor. Furthermore, it introduces by making
output current a sine-wave that achieves silent operation
and low vibration.
