The LV8824QAGEVK is a PWM pre-driver evaluation board suitable for use in 3-phase brushless motors. This evaluation board was designed based on the assumption that N channel FETs are used as the upper and lower output transistors. The rotational speed is controlled by inputting a PWM pulse or DC voltage externally and changing the duty cycle. Additionally, the LV8824QAGEVK incorporates latch-type constraint protection circuit.
