BQ25505: Ask for VBAT_OV of BQ25505

Part Number:BQ25505

Dear Colleagues

I have a question about the range of VBAT_OV of BQ25505.

On 12 page of the datasheet, the simple equation for VBAT_OV is described.

Since VBIAS is arount 1.2V, VBAT_OV seems to be bigger than 3/2 * 1.2 = 1.8V.

If then, is it possible to lower VBAT_OV level to less than 1.8V?

Actually, I want low VBAT_OV under 1V. 

Thanks
