LB1862M_09 Datasheet, PDF (1/7 Pages) Sanyo Semicon Device – For Fan Motor Single-Phase Full-Wave Driver

Ordering number : EN5657D
LB1862M
LB1962M
Monolithic Digital IC
For Fan Motor
Single-Phase Full-Wave Driver
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. The LB1862M features a lockup
detection output (RD) and the LB1962M features a rotation detection output (FG).
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 (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
