DRV8320: Transient of 28V to 48V in 1ms on power line. will IC withstand on voltage transient?

Part Number: DRV8320

I am trying to use IC in UAV application. where Power supply can provide transient of 28 to 48 V in 1ms according to MIL-STD-704D. As DRV8320 is directly on power line my doubt is whether This TI IS can withstand on some transient voltage as its range is 6 to 60V. IF not what is the possible protection or solution?

Dinesh,

Thanks for posting on the MD forum!

I will need to check with design. I’ll get back to you on Monday.

Dinesh,

For ~20V/mS we are not concerned. If this voltage range changed over a few uS then we may have more concern.

Adam,

Thank you for your answer,

Could you please tell me from which part of the datasheet I can understand the transient response of the IC.

thanks & Regards,

Dinesh

Dinesh,

We do not specify the transient response of the chip as this is not a power supply or regulator.
