LB1962M数据手册ONSEMI中文资料规格书

描述 Description

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
