LV8805SV 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 server fan and refrigerator fan.

• Built-in lock protection and auto-recovery circuit
• Built-in TSD (thermal shutdown) circuit
• Direct PWM signal input for speed control PWMIN pin
• Soft-Booting
• Soft-Switching
• Built-in Beat Lock Protection
• 1chip Driver
• NchDMOS output transistor
• FG (rotation count) output signal pin / RD (lock detection) output signal pin
• Motor startup with soft-start (SOFTST pin)
• 12V-system (Vccmax=16V)
