Bi-CMOS Integrated circuit IC
LV8806GQ
3-phase sensor-less
Motor Driver IC
Overview
LV8806GQ is a 3-phase sensor-less motor driver IC.
3-phase driver allows low power consumption and low vibration. And Hall sensor-less 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 PC fan.
Functions
• Built-in current limit circuit (Operates when RF resistance is 0.5Ω and Io=0.53A)
• 3-phase full-wave sensor-less driver
• Direct PWM input
• FG (rotation count) output signal pin
• RD (lock detection) output signal pin
• Built-in lock protection and auto-recovery circuit
• Built-in TSD (thermal shutdown) circuit

Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time.
Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current,
high voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details.
