LV88553 Description
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.
