... Ordering number : ENA2013 LV8138V Overview The LV8138V is a PWM system pre driver IC designed for three-phase brushless motors. This IC reduces motor driving noise by using a high-efficiency, sine wave PWM drive type. It incorporates a full complement of protection circuits and, by combining it with a hybrid IC in the STK611 or STK5C4 series, the number of components used can be reduced and a high level of reliability can be achieved ...
