Product Overview
Product Description
The LB11967V is a single-phase bipolar variable speed fan motor pre-driver that works with an external PWM signal. A highly efficient, quiet and low power consumption motor driver circuit, with a large variable speed, can be implemented by adding a small number of external components. This device is optimal for driving large scale fan motors (with large air volume and large current) such as those used in servers and consumer products.
Features
 
  • Pre-driver for single-phase full-wave drive
  • External PWM input enabling variable speed control
  • Compatible with 12V, 24V, and 48V power supplies
  • Current limiter circuit incorporated
  • Reactive current cut circuit incorporated
  • Minimum speed setting pin
  • Constant-voltage output pin for Hall bias
  • Lock protection and automatic reset functions incorporated
  • FG(Rotation speed detection) and RD (Lock detection) output
