Datasheet Three Phase Brushless Motor Driver BD63015EFV General Description Key Specifications BD63015EFV is a three phase sinusoidal brushless Power Supply Voltage Rating: 36V motor driver. The rating of the power supply is 36V and Output Continuous Current Rating: 1.5A (Note 1) Output Peak Current Rating: 2A that of current rating is 1.5A (peak current, 2A). PWM driving signals are generated by the three hall sensors. Operating Temperature Range: -40C to +105C Input DC voltage signal can control the rotation speed, Current Limit Detect Voltage: 0.2V10% also, you can control by the power voltage. As the Output ON Resistors (Total): 0.6(Typ) various control circuit and the protection circuit are UVLO Voltage: 6V(Typ) (Note 1) Pulse width tw1ms, duty=20% pulse) built-in, this IC can fit the various applications. It can be used for the small diameter motor module because of the small package.
