Product Overview
LV8805SV: Motor Driver, Sensor Less, Brushless, 3-Phase
For complete documentation, see the data sheet.
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.
Features
• 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
• Direct PWM signal input for speed control PWMIN pin
• Soft-Booting
• Soft-Switching
• Built-in Beat Lock Protection
• 1chip Driver
• NchDMOS output transistor
