... Ordering number : ENA1708 LV8130V Overview The LV8130V is a PWM drive pre-driver IC designed for three-phase brushless motors. This IC reduces motor driving noise by imparting a slope to the phase switching current by quiet PWM drive, and realizes high efficiency through the use of synchronous rectification. A motor drive circuit with the desired output capability (voltage, current) can be implemented by adding discrete transistors or other devices to the output ...

... Description of LV8130V 1. Output Drive Circuit The LV8130V adopts quiet PWM drive to realize low power consumption and low noise. This drive method is a direct PWM drive to reduce power loss in the output. In addition, the current-carrying angle is 150 degrees to reduce noise, and soft-switching is performed by changing the duty and imparting a slope to the current when switching the phases ...

... PRE-H output changes from low (OFF) to high (ON)) in order to realize synchronous rectification. Therefore, the relationship between the input duty and the output duty is as shown in the right figure. This input duty - output duty relationship changes according to the input frequency to maintain a constant delay time. LV8130V To PWMIN pin Input DUTY -- Output DUTY ...
