DRV8305-Q1: 6 \PWM Mode_Additional

Part Number: DRV8305-Q1


Dear, Sir.

My customer is considering the operation as blow using 6 PWM mode.

The phase A is not used(INHA/INLA = Low).

The phase B is repeating GHB = High, Low & GLB = Low, High(INHB, INLB is inverting).

The phase C is repeating GHC = High, Low & GLC = Low, High(INHC, INLC is inverting).

1. Is it possible to utilize this kind of operation?

2. If you have any attentions under this kind of usage, Please advice me.

Best Regards,

H. Sakai

  • Sakai,

    Yes the DRV8305-Q1 can support this operation. The three half bridges can operate independently of each other.

    Please note that the shoot-through protection cannot be disabled so for any half bridge, the high side FET and low side FET of the same phase cannot be ON together.
