LV88551, LV88552, LV88553, LV88554 Motor Driver, Single-Phase, PWM, Full-Wave, BLDC Motor www.onsemi.com Overview MARKING The LV88551JA/R, LV88552JA/R, LV88553JA/R and DIAGRAMS LV88554JA/R are the predriver for a singlephase 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. ON In addition, leadangle adjustment is possible by external pins. XXXXXXX Leadangle value and leadangle slant can be adjusted independently. ALYWG Thus, the device can be driven by high efficiency and low noise with SSOP20J various motors. Motor speed setting curve is adjustable with using CASE 565AP external resistor only. As a method of the rotary speed control of the (LV88551JA, LV88552JA, LV88553JA, LV88554JA) motor, directPWM pulse input.
