  • DRV8432: Maximum DC Bus Voltage Vs (abs/max)

    TI Thinks Resolved
    Part Number: DRV8432 Other Parts Discussed in Thread: DRV8412 , DRV8462 Hi, There is a small confusion on the maximum safe voltage for using this IC. Its datasheet mentions 70 V. However, its evaluation board recommends 52.5 V only. What limits the evaluation…

  • DRV8432: Permanent damage to DRV8432 when motor shaft spun.

    TI Thinks Resolved
    Part Number: DRV8432 We have an application where it is possible the motor shaft is spun with no control power to the product. At this time the motor is a generator and is converted to DC Bus power thru the flyback diodes in the DRV8432 between PVDD_x…
