      SPECIFICATION

      • Single-phase full-wave drive (16V, 1.0A transistors are built in)
      • Built-in variable speed function controlled by a thermistor input
      The LB11961 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)
      • Operates in full-speed mode when the thermistor is removed.
      • Built-in lock protection and automatic recovery circuits
      • FG (speed detection) and RD (lock detection) outputs
      • Built-in thermal shutdown circuit
