TPS53689T: CSPIN (Pin 37) functionality

Part Number: TPS53689T

Tool/software:

Hi Team,

Want to know that, whether CSPIN (pin 37) can be used as voltage monitor also? 

This pin is not mentioned as multi functionality pin in datasheet.

I am getting 12V at this pin (as output). Is this behavior expected ?

If not, then what must be the reason for this?

Below I am attaching the circuit, this OUT is going to pin 37 of controller TPS53689T, so 1V is expected, but getting 12V.

Is this schematic fine? or need to connect current sense circuitry only?

Thanks,
Siddhi
