LB11862M_0611 Datasheet, PDF (1/5 Pages) Sanyo Semicon Device – Single-Phase Full-Wave Fan Motor Driver

Ordering number : ENN7111
LB11862M
Monolithic Digital IC
Single-Phase Full-Wave Fan
Motor Driver
Overview
The LB11862M is optimal for small fan applications, especially CPU cooling fans, due to its single-phase full-wave drive
technique and the compact package.
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 commutating pole).
•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.
