Fan Motor Driver, Single-Phase, Full-Wave

LB11862MC
Fan Motor Driver,
Single-Phase, Full-Wave
Overview
Single-phase full-wave drive design and a compact package make these
ICs optimal for small fans (especially CPU cooling fans). Low switching
noise and effective motor drive are further advantages.
