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.

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
• Rotation detection output (FG)
• Hall bias pin and start/stop pin allow
   reduced current drain in standby mode
• Built-in thermal protection circuit
