INA200: Having trouble simulating the functionality of the IC

Part Number: INA200

Hello Team,

I have an issue regarding simulating a very basic circuit for checking the functionality of the INA200. I connected a 15 volt DC power supply to a 1 ohm resistor and 0.003 ohm shunt resistor in series. I'm using the shunt resistor voltage as the input to the VIN- and VIN+ pins. Knowing that the gain of the chip is supposed to be 20, I'm expecting the voltage across 0.003 ohm shunt (45mV) turns into 0.9V on OUT pin of INA200. Then, since I'm using the voltage divider with a ratio of 9-1 to connect OUT pin to COM_IN+, I'm expecting to see 0.81V at CMP_IN+; since CMP_IN+ is greater than internal 0.6V compactor reference voltage, CMP_OUT should go high. Well my problem is non of these are happening as I simulated the circuit in LTSpice. I'm getting the following:

- Shunt resistor current: 15A (which is right)

- OUT pin voltage: 4mV (which is WRONG!)

- CMP_OUT voltage: almost 0 (which is wrong) 

I have attached a snapshot of the simulation for the reference below. Please let me know what I'm missing here!?

Thanks
