TPS53681: Terminations for unused pins

Part Number: TPS53681

Hello,

My customer does not use the following pins, APWM6/BPWM3, BPWM2, VR_HOT, VR_FAULT and SMB_ALER. Can those unused pins be left floating, or some terminations are recommended?
If the latter, please let them know the recommended terminations for each pin respectively.

Best regards,

Hirano-san,

Hi, the PWM pins, as well as their corresponding CSP pins can be left floating if unused.

VR_HOT, VR_FAULT, and SMB_ALERT are all open-drain outputs and can also remain floating if unused.

Thanks,

Nastasha
