Overview
The LV88551JA/R, LV88552JA/R, LV88553JA/R and
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.
In addition, leadangle adjustment is possible by external pins.
Leadangle value and leadangle 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, directPWM pulse input.
