The LV88563JA is the pre−driver for a single−phase 24V/48V BLDC motor, which has the closed loop controller for motor rotation speed. This is available to control a motor with low vibration and the low noise. In addition, lead−angle adjustment is possible by external pins. Lead−angle value and lead−angle slant can be adjusted
independently. Thus, the device can be driven by high efficiency and low noise with various motors. Motor speed setting curve is adjustable for many variety using external resistor only. As a method of the rotary speed control of the motor, direct−PWM pulse input is adopted.
