LA6597FMC: Single-Phase Full-Wave Fan Motor Driver

The LA6597FMC drives the single-phase bipolar fan motor by means of the BTL output linear drive highly efficiently while suppressing the reactive current, in the power-saving and silent manner. With incorporated lock protection and lock signal circuits, this product is optimum for fans of car audio, projector, and VGA card where the high-temperature operation, high reliability, and low noise are required.

Features
  • Single-phase full-wave linear drive by BTL output (gain resistance 1k to 240k, 48dB)
  • Operable at low voltage and over a wide operation voltage range (2.2 to 14.0V)
  • Diffusion of generated heat: Low saturation output (Upper + lower saturation voltages: VOsat (total) = 1.1V typ, IO = 200mA)
  • Lock protection and automatic return circuits incorporated
  • FG output (Rotation detection output: Open collector output)
  • Hall bias incorporated (VHB = 1.55V)
  • Heat protection circuit
  • Small package with high heat capacity
End Products
  • Car audio
  • Projector
  • VGA card
