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).
