LV88551, LV88552, LV88553, LV88554 Motor Driver, Single-Phase, PWM, Full-Wave, BLDC Motor Overview The LV88551JA/R, LV88552JA/R, LV88553JA/R and LV88554JA/R are the pre−driver for a single−phase BLDC motor, which have the closed loop controller for motor rotation speed.
These are 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 with using external resistor only.
As a method of the rotary speed control of the motor, di...
