LB1862
Monolithic Digital IC
For Fan Motor
Single-Phase Full-Wave Driver
http://onsemi.com
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.
Functions
Support for 5V/12V dual power supply voltage
Built-in regenerative circuit allows use of reverse connection 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
Hall bias pin and start/stop pin allow reduced current drain in standby mode
Built-in thermal protection circuit
