How should I connect the /PWRFAIL and /HOT_RESET pin if it is unused?

Short GND? or Floating?

Hello Charles,

PWRFAIL is an output, so can be left floating.
HOT_RESET is an active-low input, which resets DCDC1 when pulled low. So I suggest to connect HOT_RESET to VCC to prevent it causing reset.

Regards,
Karl

There was a mistake in checking the port type of HOT_RESET.
Thank you.
