LB1962M Overview
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
- Built-in regenerative circuit allows use of reverseconnection protection diode
- Built-in Hall amplifier with hysteresis (supports core without auxiliary electrode)
- Built-in lockup protection and automatic recovery circuits
- Latch-type lockup detection output (RD) is Low during rotation and High during stop (LB1862M)
- Rotation detection output (FG) (LB1962M)
- Hall bias pin and start/stop pin allow reduced current drain in standby mode
- Built-in thermal protection circuit
