Product Overview
Product Description
The LB11970FV is a single-phase full-wave driver for fan motor.
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
  • FG (rotation detection) output
  • Thermal shutdown circuit incorporated
