LB11970RV: Single-Phase Full-Wave Fan Motor Driver
The LB11970RV is a motor driver of the single phase bipolar drive that a good direct PWM drive of the motor drive efficiency can come true easily. It is most suitable for the power supply fan of the personal computer, CPU air conditioner fan drive.
Features- Single-phase full-wave drive (16V to 1.2A output transistor incorporated)
- Variable speed function using thermistor input and external signal incorporated
- Current limiter circuit (limit at IO=480mA with RL=1Ω connection, the limiter value determined with Rf)
- Kick-back absorption circuit incorporated
- Low-consumption, low-loss, and low-noise drive enabled by the soft switching circuit during phase shift
- Regeneration Di incorporated with less external parts
- HB incorporated
- Lock protection and automatic reset functions incorporated
- RD (Lock detection) output
- Thermal shutdown circuit incorporated
