DRV8300: Bootstrap pin voltage absolute maximum rating with respect to SHx

Part Number: DRV8300

Hello,

We would like to use the DRV8300 with GVDD = 15V and SHx of maximum 60V. Is that possible ?

Regarding this, we have question about the maximum voltage of the bootstrap pin with respect to SHx :

There is 2 specs, one saying the maximum voltage on bootstrap pin is 125V, the other one saying its 21.5 (with respect to SHx).

Does this mean that we are out of specs ? (60-12 = 48V > 21.5)

Same question about the high-side gate drive pin voltage : if we are in 12V on GHx and if SHx reaches 60V, are we out of specs ? (60-12V = 48V >22V)

Thanks for your help !

Best regards,

Antoine
