DRV8323: DRV8323 - 50V or 60V max?

Part Number: DRV8323
Other Parts Discussed in Thread: DRV8301, , DRV832X

Hello -

I have custom hardware utilizing TIs InstaSPIN technology and a DRV8301 gate driver currently (plus an external current shunt amplifier for full three-phase sensing).

I am looking closely at the DRV8323 as a potential replacement, as it has three current shunt amplifiers built-in. However, the current datasheet seems to have a couple inconsistencies. It labels the device as both "6 to 60-V" and "5.5 to 50-V". The maximum ratings state 65V for both the gate driver and the buck regulator.

Which is correct? My maximum input voltage is around 55V.

Any input is appreciated.

Thanks,

Hello Asif,

Thank you for bringing this to our attention. It seems that the datasheet was corrupted and a lot of mistakes are now present. We are working to revert the datasheet to the previous state as soon as possible.

Voltage range is 6.0V to 60V with abs Max rating of 65V.

Thanks,

Matt

Hi Asif,
Please make sure you are looking at the latest revision of datasheet, April 2017. the link is: www.ti.com/.../drv8323.pdf
I skimmed through it and datasheet agrees with the values Matt have mentioned above. Thank you.

The DRV832x datasheet has been reverted to the previous (correct) state. Please check on it now from ti.com

Sorry for the inconvenience and thanks again for bringing this to our attention.

Thanks,

Matt
