Hi Keith,

What pin are you referring to for dv/dt?

Thank you,

Hello,

We're comparing it to the UCC27710 which has a specification for this.

Thank you, Keith

Hi Keith,

The UCC27710 is a half-bridge driver and the dv/dt immunity is referring to the switch node (HS). The UCC27531 is a single channel low-side driver and does not have an HS pin, so it does not have an equivalent dv/dt rating.

Please let me know if you have any further questions.
