产品信息

The LV8814J is a 3-phase BLDC motor driver which is controlled by single Hall sensor. A 180 degrees sinusoidal driving method is adopted and the IC can control motor with low vibration and the low noise. In addition, lead-angle adjustment is possible by an external pin. 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. The power element to drive a motor is built-in and contributes to high efficiency by low on resistance (0.5 Ω). The Hall sensor bias driver is equipped, and a Hall IC is supported as well. As a method of the rotary speed control of the motor, direct-PWM pulse input or DC-voltage input can be chosen.

3-phase full wave (sinusoidal) drive
Any practical combination of slot and pole can be handled. (e.g. 3S3P, 3S4P, 6S4P, 6S8P, 12S8P, 9S12P and so on)
built-in power FETs (P-MOS/N-MOS)
Speed control function by direct PWM or DC voltage input
Minimum input PWM duty cycle can be configured by voltage input
Soft start-up function and soft shutdown function
Soft PWM duty cycle transitions
Built-in current limit circuit and thermal protection circuit
Regulated voltage output pin for Hall sensor bias
Built-in locked rotor protection and auto recovery circuit
FG signal output
Dynamic lead angle adjustment with respect to rotational speed
Lead-angle control parameters can be configured by voltage inputs
