The LV88561JA/R is the pre−driver for a single−phase 24 V/48 V BLDC motor, which has the closed loop controller for motor rotation speed. This is 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
for many variety using external resistor only. As a method of the rotary speed control of the motor, direct−PWM pulse input is adopted.
Single-phase full wave drive pre-driver include closed loop speed control - high accuracy for motor speed control
Speed control function by PWM duty input (25 Hz to 100 kHz) - wide operation range
Soft start-up function and PWM soft switching phase transition - low noise and silent drive
Soft PWM duty cycle transitions - low noise and silent drive
Built-in current limit circuit and thermal protection circuit - safety
Built-in locked rotor protection and auto recovery circuit - safety
FG signal output - easy to motor control
Dynamic lead angle adjustment with respect to rotational - high efficiency
