Bi-CMOS IC
LV8227LG
Overview
For MD and UMD
System Motor Driver IC
The LV8227LG is a system motor driver IC that implements all the motor driver circuits needed for MD and UMD (Universal Media Disk) products. The LV8227LG provides a three-phase PWM spindle driver, a sled driver (as two three-phase stepping motor driver channels), and focus and tracking drivers (as two PWM H bridge driver channels). Since the LV8227LG uses Bi-CMOS process, it can contribute to further miniaturization, thinner from factors, and lower power in end products.
Functions
* PWM H bridge motor drivers (2 channels) * Three-phase stepping motor driver (2 channels)
