Ordering number : ENN6208A
LB1862
Monolithic Digital IC
LB1862
Fan Motor Single-Phase Full-Wave Driver
Overview
Single-phase full-wave drive design and a compact package
make this IC optimal for small fans (especially CPU
cooling fans). Low switching noise and effective motor
drive are further advantages.

Features
• 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
