Ordering number : EN6208B
Monolithic Digital IC
LB1862
Overview
For Fan Motor
Single-Phase Full-Wave Driver
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
