Unfortunately, I didn't have enough information to provide a specific answer to your question.
However, if specifically, you are referring to an "Undervoltage Protection" (UVP) schematic and you'd like to use the TPS2HB50BQPWPRQ1 Load Switch from Texas Instruments as part of your design provided, then a simple strategy for establishing UVP could be:
Connect SEL1 and SEL2 (pin 14 and 15) to a voltage supervisor IC or a microcontroller GPIOs. The SEL pins allow you to select the threshold for undervoltage protection.
The voltage supervisor IC or microcontroller controlling SEL pins would monitor the input voltage and, in case of undervoltage, change the status signals to the SEL pins, triggering the undervoltage protection feature of TPS2HB50.
Configure EN1 or EN2 (pin 4 and 13), which are the enable pins of the device. These can be driven high to enable the device and potentially be controlled by the same microcontroller that monitors your voltage.
Remember to connect your ground pin (GND or pin 1) to the common ground of your circuit to establish a common reference for all your voltage levels.
Note: This is a general guideline. Your specific implementation may vary depending on your design requirements such as the voltage level you want to protect against and the specific behavior of your protection system.
