LA6587FA: Single-Phase Full-Wave BTL Fan Motor Driver

The LA6587FA is single-phase bipolar fan motor is driven, through BTL output linear drive, at high efficiency, low power, and low sound by suppressing the reactive power. Lock protection, rotary signal (FG, 1/2FG) circuits are incorporated, which is optimum for the notebook PC, consumer equipment power supply, car audio system, CPU cooler, etc. that require high reliability and low noise.

Features
  • Single-phase full-wave linear drive by BTL output (gain resistance 1kΩ-360kΩ, 51dB)
  • Low-voltage operation possible, with wide operating voltage range (2.2 to 14.0V)
  • Low saturation output (Upper + lower saturation voltage : VOsat (total) = 1.1Vtyp, IO = 100mA)
  • Built-in lock protection and automatic reset circuits
  • Built-in FG & 1/2FG outputs
  • Built-in Hall bias (VHB = 1.5V)
  • Thermal protection circuit
  • Extra-small package (MSOP10)
Applications
  • Consumer equipment power supply
  • CPU cooling system
  • Car audio system
End Products
  • White goods
  • Notebook PC
  • Car audio
