LB11961V - Single-Phase Full-Wave Fan Motor Driver

Features

  • Single-phase full-wave drive (16V, 1.0A transistors are built in).
  • Built-in variable speed function controlled by a thermistor input The LB11961V can implement quiet, low-vibration variable speed control using externally clocked high side transistor direct PWM drive.
  • Built-in regenerative diode (Di); only requires a minimal number of external components.
  • Built-in HB.
  • Minimum speed setting pin (allows full-speed mode operation at startup).
