DRV8332 has high current in 50% duty cycle

Hi.

I am trying to develop 3 phase bldc motor drive board by trapezoidal commutation with hall sensor. I am using DRV8332 drivers to drive motor but the driver is high current, about 1.2A, in 50% duty ratio. I think the driver has low current in 50% duty ratio. I don't know why it is. It looks like normal except the high current problem.

Best regards.

Lee.
