TPS53667: resistor between TSEN and GND

Part Number: TPS53667

Hi expert,

I check the reference circuit and always find a resistor like 10k or 121k from TSEN to GND, could I remove it?

If not, why do we add it here?

    Hello, 

    TSEN should be around 0.8 V and will be pulled high to 3.3 V by controller if there is an issue with temperature, which needs the resistor there. If the resistor is not there, then the signal would be left floating. I would not remove the resistor. 

    Best,
