LV8804FV: Motor Driver, Sensor Less, Brushless, 3-Phase

LV8804FV is a 3-phase sensorless motor driver IC. 3-phase driver allows low power consumption and low vibration. And Hall sensorless drive allows reduction of the size of a motor system. This IC is suitable for use in products which require high reliability and long life such as note server fan and refrigerator fan.

特性
  • Direct PWM three-phase sensorless motor driver
  • Built-in current limit circuit (Operates when RF resistance is 0.25Ω and Io=1A)
  • Built-in lock protection and auto-recovery circuit
  • Built-in TSD (thermal shutdown) circuit
  • PWM(Pulse width Modulation) control
  • Soft-Booting
  • Soft-Switching
  • 1chip Driver
  • NchDMOS output transistor
  • FG (rotation count) output signal pin
  • Minimum speed setting MINSP pin
  • Motor startup with soft-start (SOFTST pin)
  • DC voltage input for speed control
  • 12V-system (Vccmax=16V)
