LV88551 Single Phase BLDC Motor Driver from ON Semiconductor

These 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, direct-PWM pulse input.

Features
Single−phase Full Wave Drive Pre−driver Include Closed Loop Speed Control
Speed Control Function by PWM Duty Input (25 Hz to 100 kHz)
Built−in Current Limit Circuit and Thermal Protection Circuit
Built−in Locked Rotor Protection and Auto Recovery Circuit
Lineup of Different Closed Loop Gain Selection
