LV8824QAGEVK

LV8824QA 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. LV8824QAGEVK evaluation board (EVB) provides a quick and easy evaluation of the functionalities. User needs to prepare an external power supply (7V-33V) for evaluation. EVB has 2 connectors for BLDC motor, 1 connector for power supply and 1 connector to monitor the control signal and a daughter board for GUI. In addition, it can provide the platform to evaluate the performance with using the speed control IC LB8503V.

• Provides an integrated development platform to drive three phase BLDC motor
• Daughter board can communicate with the PC by graphical user interface (GUI)
• An example of small PCB layout within a circular shape
• Screw connectors to connect a motor and a power supply easily
• Optional pads for higher power FETs
