LB1962M

Ordering number : ENN5657A LB1862M, LB1962M Monolithic Digital IC LB1862M, 1962M Fan Motor Single-Phase Full-Wave Drivers 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. The LB1862M features a lockup detection output (RD) and the LB1962M features a rotation detection output (FG).
