JAJSRQ5A October 2023 – December 2023 TPS3762
PRODUCTION DATA
Open-drain output requires 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 will have a higher voltage drop affecting the output voltage high. The open-drain output can be connected as a wired-AND logic with other open-drain signals such as another TPS3762 open-drain output pin.
