ADVANCE INFORMATION
The open-drain output pins require an external pull-up resistor to hold the voltage high to the required voltage logic. Connect the pull-up resistor to the proper voltage rail to enable the output to be connected to other devices at the correct interface voltage levels.
To select the right pull-up resistor, consider system VOH and the Open-Drain Leakage Current (Ilkg) provided in the electrical characteristics, high resistors values have a higher voltage drop affecting the output voltage high. The open-drain outputs can be connected as a wired-AND logic with other open-drain signals such as another TPS3710x-Q1 open-drain output pin.
