7.3.2.3 OTW Pin

OTW reporting indicates the device approaching high junction temperature. This signal can be used with MCU to decrease system power when OTW is low to prevent OT shutdown at a higher temperature.

No external pull-up resistor or 3.3V power supply is needed for 3.3V logic. The OTW pin has an internal pull-up resistor connecting to an internal 3.3V to reduce external component count. For 5V logic, an external pull-up resistor to 5V is needed.
