• 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
