LB1962M Description
ENN5657A LB1862M, LB1962M Monolithic Digital IC LB1862M, 1962M Fan Motor Single-Phase Full-Wave Drivers Overview Single-phase full-wave drive design and a pact package make these ICs optimal for small fans (especially CPU cooling fans). Low switching noise and effective motor drive are further advantages.
LB1962M Key Features
- Support for 5V/12V dual power supply voltage
